Generally speaking, most of the stuff on this site can be applied the Hot Rod Deville, some of this can be applied to the Blues Deluxe/Deville, and very few of it can be applied to the Blues Junior or Pro Junior. They may be a part of the 'Hot Rod' lineup, but internally the BJ and PJ are totally different amps. The Blues Deluxe/Deville have quite a few similarities, but they also have some differences. If a mod or fix can be applied to one of those amplifiers, I'll mention it somewhere atop the page. Are the Hot Rod Deluxe/Deville All Tube?
In the true sense of the phrase 'all tube?' The rectifier, which converts AC to DC, is solid state; the effects loop is solid state; and so is part of the Reverb unit. Most modern day amplifiers use solid state rectifiers and reverb units. Many vintage amplifiers have tube rectifiers, but they're generally considered unreliable. There are many classic Fender amps which have a SS rectifier, the blackface Twin Reverb being one. Solid state rectifiers don't 'break up' as early, allow more clean headroom, and provide less compression than their tube counterparts. This may or may not be something you're interested in.
The reverb driver and recovery are also solid state, but use a real spring reverb pan like those found in Fender's more expensive amps. This may be an 'issue' to the tube purists. Both the reverb and effects loop use the same type of high quality op amps. The signal path itself (preamp/poweramp) is all tube. What about the More Drive? A lot of people have heard that the More Drive is solid state, or that it uses solid state components. The More Drive uses a pair of J111 switching JFETs (a type of transistor) to bypass R23 and R24—two 100KΩ resistors that are in series with V2A and V2B's cathode capacitors.

Cathode caps simply increase gain by reducing degeneration (or local negative feedback), by shunting AC frequencies across the bias resistor. They're very common in both tube and solid state amps.
A segment of the Hot Rod's schematic has been simplied for clarity, but not altered. The More Drive circuitry has been shaded.
When the More Drive is not selected the J111 JFETs react no differently than two very large resistances. When the More Drive is selected a DC voltage is sent to the gate of both JFETs. This causes the drain and source to act like a closed switch, and the J111s turn into a dead short. As a result they jumper R23 and R24, turning the previous 100KΩ of resistance into zero ohms. Now the negative plate of the cathode caps are at ground potential, which is where they're supposed to be.
As a result, the gain of both stages is practically doubled and V2A & V2B (a preamp tube) are pushed into distortion. The increase in distortion is tube generated, and is in no way solid state. Solid state components got their bad rap from how they distort when used for amplification. The JFETs used by the More Drive do not amplify, and are nothing more than a switch.
They color the sound no more than a resistor, or a piece of wire would. If for whatever reason you wanted a permanent More Drive sound, just take two pieces of wire and jumper out both 100KΩ resistors. So despite what some people assume, the More Drive is all tube. A JFET 'Shunt Switch' is used because it's switch element is extremely quiet and produces no modulation or any other unwanted effects. When cathodes are bypassed we're dealing with much more gain. The more drive significantly raises the noise floor of the amp. This means more hiss, buzz, and mechanical noise will be amplified through the speaker.
A relay would have been too noisy since it's mechanical—the relay's pole will bounce when it slams into the contact; resulting in a clearly audible noise. You can sometimes hear this when switching channels at low volumes.
The JFETs themselves also cost less than a quarter, while the relays are at least several dollars each. What's the difference between the Hot Rod Deluxe and Deville? I once heard someone say, 'the Deville is just a Deluxe with more speakers.' Not totally true, but closer to the truth than you probably think.
In fact, the Deluxe and Deville are so similar that Fender uses the exact same printed circuit board (PCB) for both models. The Deville's preamp, reverb, effects loop, and phase inverter are all exactly the same as the Deluxe's. So any Deluxe mods done to any of these parts can also be done to the Deville. On first glance even the poweramp has a truly uncanny resemblence, though it's actually slightly different.
The main difference between these amps is the power supply, which handles 50 more volts than the Deluxe's power supply. This change dictates almost every other anomaly of the Deville. Naturally, the power transformer is a different model, as one of the secondaries must put out the higher voltage. The filter circuit has more caps to handle the higher voltage, and a few bleeder resistors are employed to help drain residual voltage once the amp is turned off. The output transformer is different, as it needs to handle 60 watts, and it has an additional 2 ohm tap which is only used by the 4x10 model. The bias circuit is filtered a little more to reduce hum, and the +/- 16V supply (powers the effects loop, channel switching, and reverb) uses the better 330 ohm power resistors instead of 470 (R78, R79).
Finally, as you've probably guessed, the Deville has more speakers that together can handle 60 watts. Why a tweed cabinet with blackface tolex and grill? The styling of the Hot Rod Deluxe/Deville, as well as '96-Present Blues/Pro Junior, is based on a short-lived tweed cabinet/black tolex combination that was used in the mid-60s. I'm not sure if any vintage Deluxes ever looked like the modern Hot Rods. Before '60 all Deluxes were tweed.
From '61-'62 Fender switched to 'blonde' coverings. Then from '63 to around '68 Fender went blackface, before setting into the silverface style for most of the 70s. Below are pictures of a modern Hot Rod Deluxe compared to a rare 1964 Champ with the original styling.
A new Pro Junior almost looks totally identical to this Champ. Modern Hot Rod Deluxe 1964 Fender Champ. If you have an older amp (usually pre-MIM) the easiest way to determine is to look at the chart below. Inside the cabinet is a little sticker (pictured above), usually to the right of the speaker. It should say 'quality assurance' on it, and have someone's handwritten initials. Look for a two letter code on the bottom line.
The first letter symbolizes the year it was made, the second letter the month. My amp says 'LA,' so it was made in January of 2001. If it says 'JF', then your amp was made in June of 1999.
First Letter G = 96 H = 97 I = 98 J = 99 K = 00 L = 01 M = 02 Second Letter A = JAN B = FEB C = MAR D = APR E = MAY F = JUNE G = JULY H = AUG I = SEPT J = OCT K = NOV L = DEC Quality Assurance stickers were used in Pre-MIM Hot Rods, and allowed users to determine the month and year their amp was manufactured. Fender removed the Quality Assurance tags around the time production was moved to the Mexican factory. When asked about the removal of these tags, a Fender employee said: 'The QA tags also no longer contain Date codes. That used to be a Safety agency requirement, but we have moved out of the dark ages and actually track by computer and other methods now.'
Fender now uses the serial number on the back panel to date their amps. Unfortunately the serial # has 'no meaning,' and access to the database that deciphers the numbers 'isn't available to the public.' Also, the earliest Hot Rod Deluxes were made in 1996, and had a '50th Anniversary' logo on the back.
Since this amp is arguable the most popular in the world, I'd hold on to the '50th' amps as they may become collectable. Which preamp tubes are V1, V2, and V3? What do they do? V1 is the first preamp tube, and is the most tonally important as it establishes the basic sound of our amp—every subsequent gain stage is simply making a copy of the first gain stage. Part of V2 is used exclusively by the Drive channel, so if you're battling the Drive channel's demons you may try using a lower gain tube in this slot. Many feel this helps smooth out the Drive channel, and gives an overall more 'bluesy' sound.
V3 is the phase inverter, which makes sure the powertubes are running 180 degrees out of phase. Using a lower gain tube here may help tighten things up, and some believe it gives the Hot Rod a more vintage-like feel. It's been asked if V2 affects the clean channel—the answer is YES. Most people don't realize that the 12AX7 triode and its family (12AT7, 12AY7, etc) are actually two separate tubes inside one enclosure. For this reason the 12AX7 family are known as dual-triodes. These 'separate' innertriodes are differentiated on schematics by the suffixes A and B, but collectively are inside the same tube. For a better understanding take a closer look at your preamp tubes.
At the right angle you'll be able to see two identical triodes mounted side by side on spacers. Now that we know where the 'A' and 'B' came from, lets map out the Hot Rod Deluxe/Deville's preamp so we can better understand how our tone is shaped. The first gain stage is called V1A, and it amplifies an unaltered version of our guitar's signal. Immediately afterwards are the volume and drive controls (the drive is called 'gain' on the graphic). As you may know, the volume is only used by the clean channel, and the drive control is only used by drive channels; but in reality the drive control is not any different than the volume control.
The Drive simply pushes V1B and V2A into distortion, while the volume control does not. When we turn the Drive to 7, the preamp tubes are seeing the same amount of signal as they would with the Volume set to 7. So we can play at a reasonable volume, the Master volume grounds off much of the excess gain later in the circuit. Our signal is then reamplified by V1B, to make up for any insertion loss (or signal loss) caused by the volume and drive controls. The next few steps are pretty straight-forward. The 'tone stack,' which you probably correctly guessed were the tone controls (Treble, Middle, & Bass) follow.
Afterward V2A compensates for the insertion loss caused by the tone stack. What happens next will be dictated by which channel we're using. If we're using the clean channel, then V2B is bypassed and the signal is sent straight to the power amp.
(The power amp consists of the phase inverter, the power tubes, the output transformer, and the speaker—respectfully.) If we're using the drive channel, then another gain stage (V2B) is inserted into the chain. This adds more gain and helps push the poweramp into saturation (or distortion) earlier. Even though V3A and V3B use 'preamp' tubes, it's actually considered part of the poweramp. It even distorts differently than V1 and V2. In conclusion, we've shown that all the preamp tubes are interconnected in the circuit, and switching one tube will affect the tone of all channels. Why don't they call them the 'F.A.T' Series anymore? Fender's pretty strict about their warranties, so keep ALL your papers.
In the USA, your amp must meet a few requirements. (Other countries may have different warranty requirements). You must have the original receipt and be the original owner, or have the original owner's receipt signed over to you. (Basically, the original owner signs their name on the back of the receipt and dates it.). The amp must have been bought from an authorized Fender dealer. No used Fender's from non-authorized dealers.
If bought used from an authorized dealer, then that dealer is responsible for making sure you have a warranty. Amp was bought from authorized dealer within the last 5 years.
(Tubes and speaker are only under warranty for the first 90 days.). Any fixes must be done by an authorized Fender repair service.
Anyone else, no matter how professional, will void the warranty. Any previous mods of any type will void the warranty. (Warranty covers manufacturing defects only.) Does your amp not meet these requirements? Let's fire up that soldering iron and have some fun! How do I contact Fender for Customer/Technical Support? I often hear people complain that they can not get a hold of Fender's customer support, especially on Harmony Central's user reviews.
The fact is, Fender did not deal with customer support through. They had a second website, which was totally dedicated to locating authorized repair centers, schematics, instrument wirings, and answering other frequently asked questions—generally, the questions Fender gets bombarded with from all over the world. Fender has now moved the content of mrgearhead to The phone number for Fender's Consumer Relations Dept. Is 480-596-7195.
Before you call, realize that Fender does most of its customer service through authorized repair centers. I also have Fender's Customer Service email, which is hard to find, but only use it if you genuinely have some sort of real problem or a serious question. Do not email them if you want to know if a Jensen speaker sounds better than a Celestion, or if you have a question on using your multi-effects processor with your Fender amp. These are not real customer support questions; ask those types of questions in the. If you do ask a question like those, don't be surprised if you never get any response. Also, don't use this to complain about the touchy master control or the plastic input jacks—trust me, Fender knows.
People have been complaining for years. Why would they change anything on the #1 selling Fender amp of all time? (According to Shane Nicholas, Marketing Manager of Fender amps.) If you honestly have a problem that only Fender's support can answer, then contact them through, otherwise use the. FYI: I've heard that Fender has a '3 Strikes' policy. If your amp is under warranty, and an authorized tech has attempted to repair it three times and failed, Fender will replace your broken amp with a new one.
While I've heard evidence to support this, I haven't officially heard it yet from a Fender representative. So ask your local authorized Fender repair person. Was a tweed version made of the Hot Rod Deluxe/Deville?
'The extension cabinet was built by Kim Reynolds in Northern CA. Reynolds is a master wood craftsman and guitarist who built two cabinets (one for himself and one for me). The cabinet is solid maple (birds-eye maple sides - it looks amazing up close) and features two 12' Eminence speakers arranged vertically with foam sound insulation inside to prevent acoustic wave pooling. The bottom speaker is the Eminence Legend V12. The top speaker is the Eminence Legend GB12.
The two speakers have different tonal characteristics and together in this closed back cabinet sound huge and absolutely amazing.' - Dan Sheridan. It's well known that the stock speaker is an Eminence, but which one exactly? (Webmaster note: not necessarily true. My stock speaker was a Celestion G12P-80, which I thought didn't sound too great and swapped it out with the famous Celestion Vintage 30.) I've often heard it referred to as 'brown label,' 'gold label,' or 'special design,' but to find out for sure I contacted Eminence's customer service. With the exception of the Fender Special Runs, the speaker which has always came stock in the Hot Rod Deluxe is the Eminence Legend 125.
Its power is rated at 50w and has a ceramic magnet. (The non-special design Legend 125s are rated at 75W.) The Limited Edition (polished maple cabinet) and Brown tolex versions have a Jensen C12N (ceramic magnet). The Lacquered Tweed Hot Rods have a Jensen P12N (alnico magnet). The black and blonde tolex Hot Rods come with the Eminence Legend 125. Why do the OEM Groove Tubes have different colored labels? Groove Tubes uses a number and colors color system to represent how early theirs tube break up into distortion.
The blue labeled Groove Tubes break up the earliest, and are numbered 1 through 3. They're supposed to be used more for blues. The white labels have a medium breakup, are labeled 4 through 7, and are the most common found in stock Hot Rod Deluxes.
The red labels have the least amount of breakup, meaning the most clean headroom, and are numbered between 8 and 10. They're for really clean playing, or for someone who only uses the clean channel with a distortion pedal. With the exception of the 6L6GE, Groove Tubes does not make their own tubes. We can clearly see this tube was made by Sovtek; Groove Tubes just slapped their logo overtop of it. Mauser rifle serial number search. They are a tube matching service. Buying a set from GTs will cost you more than buying a matched set from pretty much anyone else.
In my opinion, it is not worth it. There are many great sites that sell the same tubes as GTs, and cost a lot less. A white labeled Groove Tube. This is a complaint that I often hear.
The reason it's sometimes difficult to resolve is because there are so many different things that can cause a loss of volume. Often times people will mess around with speaker and accidently plug into the wrong speaker jack. This isn't dangerous, but it will cause a great deal of volume loss.
The internal speaker should be plugged into the internal speaker jack, the one on the left, and NOT the external speaker jack on the right. (See above picture.) If we plug into the external speaker jack the volume will go way down. 'But what if that's not the problem?' Take it to a tech. If, and only if, you're technically inclined and have good problem solving skills, then you could try the following steps to resolving the problem.
(I do not go into a lot of detail, like safety and the such, because I assume you already know all that stuff.) Plug your guitar into the 'Power Amp In' of the effects loop. Is there still a big loss of volume? (Note that plugging into the Power Amp In will not be as loud as plugging into the input jacks, though it should be obvious whether you can still hear the problem.) Remember, the effects loop is placed between the Preamp and Power Amp!
If the amp sounds normal when plugged into the effects loop, then the problem is in the preamp; else, if you still hear a big loss of volume, then the problem is in the power amp! Most of the time the problem is in the power amp, though my Hot Rod once had this problem and it was in the preamp. Always assume the tubes, as they cause the vast majority of problems in tube amps. This is why tubes are only used in a select few products. For this reason, you should always keep a spare set of tubes around (for all your amps) for whenever a problem appears. Most of the time it will be a bad tube. Trouble Shooting the Preamp: If you have an oscilloscope and a function generator, then this should be very easy for you.
For the rest of us, you'd be surprised by how much you can do with just an electronic multimeter and the schematic. Is the problem only in the Drive channel? Then the problem is around V2B, turn the amp off, drain the filter caps, and check the continuity of parts around V2B.
Simple enough. Often times when we check the plate voltage of the preamp tubes, we'll hear a 'pop' as the red probe touches the solder joint—this is normal. If you check the plate voltage of a certain gain stage, and you read zero volts, then a plate load resistor has come open, and we've found our problem. Check the plate voltage of V2A, if you hear a loud/clear 'pop' then the problem is before V2A— check V1B for the same thing and keep going back until there's no 'pop'—or until it's very quiet.
Once you've figured out which gain stage the problem is located in, check the continuity of all the parts in that gain stage—sometimes a trace or solder joint has just come open. I was able to isolate the problem all the way down to a relay (K1), which lost its ability to make contact with its internal conductor. What I was hearing through the speaker was an 'echo' of the signal, caused by less-than-perfectly decoupled gain stages. Trouble Shooting the Power Amp: There are usually a couple things that cause a loss of volume in the power amp. The first is a shorted tube, which are known to char the screen resistors. I documented such a case in the.
The other is the 82K resistor on the phase inverter coming open, so that only one power tube is working. I also documented such a case in the. Another, though very rare case, would be a damaged/shorted output transformer. You should be able to tell if there's a short in the OT by checking the plate voltages, and then checking if there's any DC voltage on the secondary—which there should not be.
The last resort would be a blown speaker. How do I replace a blown jewel light? Okay, I know this is pretty obvious. The main question is what kind of bulb to replace it with and where to get it. You can find the bulb at your local RadioShack.
It's a #47 bayonet lamp, and two cost about US$1.50. There's not much to replacing the bulb, but if it's your first time it may be a little tricky.
First, you unscrew the jewel cover. Second, you push down on the bulb because there's a spring underneath it. Third, you twist it with your finger in a counter-clockwise motion.
The bulb will pop out. If you have trouble getting hold of the bulb, then use a piece of duct tape to help you get some grip. When you replace it just push it down and turn it clockwise. NOTE: If you want a different color jewel cover, you can get them from AES under 'Guitar Amp Parts' - 'Jewels, Etc.' (They cost under US$2 each.) I've heard that purple was the coolest looking, but when mine lit up it looked pink!;). This question has come up quite a few times.
Fender Hot Rod Deluxe Serial Number Lookup
Obviously it can be done, but it'll take a bit of elbow grease. Firstly you must relocate all the tubes behind the chasis. You'll have to make room for them, so expect to move the output transformer and choke. It'd also be a good idea to plug up those old tube sockets. Doug at Vintone has pulled this one off. Above is a picture of the final product. Though it would be much simpler (and less expensive) to just use the extension speaker out, and hook it to an external cabinet.
What are the differences between the Hot Rod Deluxe and Blues Deluxe? By Steve Dallman. The two are similar in some ways and quite different in others. The obvious differences are the drive channel and 'more' drive.
Both amps are sort of takes on a 59 Bassman according to Fender with the added drive, reverb and effects loop. That may be a stretch.
'Normal' Fenders, such as 'black face' and 'silver face' Twins, Bandmasters, Bassmans, Deluxe Reverbs and the like have a gain stage, the tone stack (which introduces a lot of signal loss) and then a recovery gain stage. From there there will be a mixing stage for the channels and reverb and on to the power amp. In the BD and HRD there are 2 gain stages preceding the tone stack. This helps create the blusier preamp breakup similar to a 59 Bassman. The tone stacks are sort of a cross between a 59 Bassman and a standard Fender. Next comes the drive stage.
In the BD it is a rather anemic single tube stage. In the HRD both halves of V2 are used. In the BD there is half a tube unused. How much you like the distortion in either amp is really a matter of taste. The first stages are classic Fender except the BD uses a 22uf cathode bias cap while the HR uses a larger 47uf, which will create a bit more low end. Coupling cap next is.01BD Vs.022 in HRD. Still a little more low end in the HR.
The bright switch in the BD is next. This is a non-standard Fender design, which bypasses a 100k resistor with a 750pf cap. As the 100k resistor is attached to the 250k-volume control, it is only effective in clean mode. The drive control in the HR is between the first and second stage. The second stage is unbypassed in both amps. In the HR the bright switch is a.068 cathode bypass cap that is non-functioning in drive mode. The tone stack follows the second stage.
They are identical except the HR uses a 130k mid slope resistor, while the BD is 100k. This will create a little less low end in the HR. The drive control precedes the 3rd stage in the BD, a standard Fender bypassed gain stage. The 3rd stage is used in both clean and drive in the BD. In the HR the 3rd and 4th stages are used in drive only.
This tube is unbypassed. In More drive a 1uf-bypass cap is switched in on the 3rd stage and a 22uf bypass cap is switched in on the 4th stage.
(The 4th stage is not used in the BD, but is just waiting to be modded in.) Note on bypassing. The gain in a tube stage is set by 3 components, the plate resistor, (typically 100k in Fenders, larger for more gain) the cathode resistor, (typically 1.5k in Fenders, smaller for more gain) and a bypass cap that bypasses the cathode resistor. The cathode cap is not always used but when it is, it will increase gain in different frequency ranges. 22uf will increase gain across the entire guitar spectrum.
Smaller will only raise gain in higher frequencies. The master for the drive channel follows in both amps. From there the amps are nearly identical, except the HR has somewhat fuller reverb due to the design of the reverb return. (The reverb circuit and the effects loop are solid state.) The HR has an extension speaker jack that uses the 4- ohm speaker tap on the output transformer. The BD has this tap but it is not used (but could be added by a tech.) In general these amps are similar. The BD will not stay as clean at higher volumes due to the 3rd stage always being active. The HR has 'improved' distortion (drive) with 'more drive' added.
The HR has fuller reverb and an extension speaker jack. Both are good designs with plenty of classic Fender tone.
There's even a new and updated name plate for the version III of the Hot Rod Deluxe. Fender Hot Rod Deluxe III Combo Let's assume for a second you've never seen or heard one of these amps. This would mean that you've barely been to a gig, jam, rehearsal room or music store for over a decade. They're everywhere - the most popular, semi-pro and pro valve amps on the market, and they remain the cornerstone of Fender's modern amp line.
The watershed year was 1995. Ritchie Fliegler arrived from Marshall and promptly discontinued Fender's most successful amps of the time - the Blues DeVille and Deluxe - and evolved them to Hot Rod status, complete with an extra drive stage. 'The Hot Rod's normal channel is a brilliant base for pedals, thanks to its high headroom and dynamic range.' Now for 2010, they receive a version III update, which includes a new top panel, different pot tapers, 'tighter' overdrive and new speakers in certain models.
Here we have the biggest seller, the 40-watt Hot Rod Deluxe III. The latter black and silver Hot Rod colour scheme (the first Hot Rods were Tweed) comprises a simple black Tolex-covered quality ply cabinet, fronted with a silver grille cloth. It's a narrow-panel, top-loading fifties-style cab, with mid-sixties livery, basically. The bigger change here is the control panel, which to date has been silver, with the decals facing backwards. Version III brings a black panel with white lettering with the decals facing you when you stand in front of the amp. It might seem like a small thing, but the legion Hot Rod users out there will tell you that this will make a massive improvement to legibility either on dim stages, or under reflective lighting.
The controls themselves remain as the previous Hot Rod Deluxe, with its dual-channel set-up, powered by a trio of 12AX7 valves. There are two inputs, the first at 1 meg-ohm, as is usual in most quality valve amps, and the second lower than that, which has the effect of attenuating high-end and level.
If you have overly bright, or mega high-output pickups, or perhaps you want a warmer sound for jazz, for example, it's worth experimenting with the second input. The normal channel has a single volume with no master control, and there's a bright switch for extra zing and presence should you so desire. We had hopes of a separate master volume added to this channel to increase versatility, particularly at lower levels and make it easier to balance with the drive modes, but Fender has chosen to keep it simple.
The second channel is all about overdrive, with the additional mode 'More Drive' selectable either via the top panel, or via the included footswitch. The result is three sounds at your feet - clean, drive and more drive - via the included, and much improved two-button switch. The two principal electronic changes over the previous Hot Rods are firstly that Fender claims to have 'tightened' the overdrive: 'More attack and less slop on the lower strings,' according to Fender senior product manager and amp expert Shane Nicholas. Secondly, the volume and treble controls have a new taper, designed to make the lower regions of the control more gradual. 'The Hot Rod Deluxe had a reputation among some users for being quiet on one-and-a-half and loud on two,' continues Nicholas, 'so we changed the taper of the control for smoother response. We did the same thing with the treble control. This is especially appreciated by players who use the amp at home, yet it won't bother the gigging guitarist.'
We do wonder who buys a Hot Rod Deluxe to use purely at home, under two on the volume - it's a very loud amp - but nevertheless, Fender clearly thought that it was a big enough deal among current players to make the change. 'Drenched in reverb, what emanates from the combo is an almost 3D quality that makes you want to call-and-answer with chords and melodic phrases all day long.' Fender approaches its series effects loop with two jacks titled Preamp Out and Power Amp In; think of them as send and return respectively. There are no designated level controls, so you might have volume issues with overly quiet pedals if they don't have their own level attenuation. This is no different than plugging certain pedals straight in the front-end of the amp, of course.
And when you do, the Hot Rod's normal channel has always been a brilliant base to layer pedals on, thanks to its high headroom and dynamic range - version III is every bit as good as its predecessors in that respect. On the inside, this is very much the modern valve amp; a custom PCB layout so they can be manufactured to a consistent quality in high numbers. Well designed and put together, this isn't circuitry as art, but the seemingly countless Hot Rods out there are testament to its general road-worthiness. The biggest issue that we're aware of to date is with the reverb, where the tiny wires in the tanks themselves can come loose. Thankfully it's a safe, easy and cheap fix, if you need to.
The reverb in the Hot Rods isn't valve-driven as it is in higher-end Fender amps, such as the Super Sonic and some vintage reissue and custom models. Instead it has its own little op amp to drive the signal to and from what some see as a clunky, mechanical relic from yesteryear; others as the absolute and only way to create reverb in guitar amps. The other significant change in the version III Hot Rods is that there's now a Celestion speaker on the end of the dual-6L6 40-watt power stage, instead of the previous Eminence driver. Replacing the speaker has become a common mod for Hot Rods, so Fender has chosen to change it to a 12-inch called the G12P-80.
Not a million miles from Celestion's current Seventy 80 model, it has an 80-watt power handling capacity and 98dB sensitivity with a 31oz ceramic magnet. So let's see how it Sounds You haven't heard clean until you've heard it from a 6L6-equipped Fender amp, and short of the hand-wired Custom stuff, this is as good a place as any to get it.
The Deluxe III's normal channel has all the shimmer to make single-coils sparkle, but it's the room-filling bass, coupled with the slightly scoopy mid-range that completes this sound. We have to note that all of the above is significantly improved when using a high-quality cable between guitar and amp.
Drenched in reverb, what emanates from the largely open-backed combo is an almost 3D quality that makes you want to call-and-answer with chords and melodic phrases all day long. As you turn up the wick, you can introduce some light overdrive, especially with more powerful pickups, but we're talking about gig volumes for that. With or without pedals, this channel alone will out-shout most 'normal' volume acoustic drummers.
The reverb is sweet, spacey and old-school evocative, but it can start to feel unrefined as you go much past three and dig in hard, certainly when compared with more advanced circuits in amps such as Vox's AC30 Custom and the Mesa Lone Star series. It's still infinitely better than many of the digital reverbs cropping up in some low/mid-priced valve amps, however. The drive channel is where things have changed most over the previous Hot Rods. There was a tendency for the overdrive to become somewhat ragged sounding, especially with single coils and your guitar controls maxed-out. Heading straight for 'more drive', the Deluxe III returns a notably richer distortion with what feels like a more musical harmonic structure. It hangs on to the bottom-end with more authority, too, so it doesn't become muddy unless you want it to by adding tons of bass.
There's still plenty of high-end, which is good news for more powerful humbuckers and darker sounding guitars in general, though with vintage-style Strats and Teles, you'll be reaching for the tone pot on your guitar for fatter, modern-style gains. There's tons of overdrive on tap; full, saturated Gary Moore-type blues that can also veer into that mid-rich 'boutique' area, and heavy rock riffing if you need it, with the mids dialled down. Going back to the Drive mode in channel two - the LED goes green from red - the gain level drops off to a bluesy/rocky crunch. Depending on guitar, it can span softer, Hendrix and SRV-type chordal stuff, through to more strident and spiky punk-derived Arctic Monkeys/Strokes sounds, then on to smoother classic rock rhythms. There is some compromise involved in the shared EQ and single drive pot, but to us the relationships make sense when flicking between modes.
We find that putting the drive control somewhere between five and nine (it goes to 12) covers most blues, classic rock and heavier/more contemporary rock applications, depending on the guitar you're using. Whether it's the revoiced overdrive or not, this speaker feels like a real improvement over the previous Eminence model. It's less spiky in the upper mids and low trebles for the most part - but as we say, do watch those tone controls with bright guitars. What a superb amp. Fender has done the smart thing in providing a wide range of tones from classic clean, to more saturated, harmonic drives from one simple row of knobs.
We know that from Hot Rods past, of course, but the updates - the more focused overdrive, easier-to-read-controls and the improved speaker - are all changes that players are going to feel and hear straight away. The caveat is that the Hot Rod Deluxe III requires that you interact with it as an instrument, rather than simply treating it as a noise box. With neither independent EQ for each channel, nor dual gain pots in the overdrive modes, the true extent of this amp's versatility lies in your guitar's controls, and your fingers of course. Some amps don't offer that kind of dynamic and flexibility, and it's fair to say that not everybody likes to play that way. For those who do The Hot Rod Deluxe has become popular for good reason, and this version III update will only continue that excellent reputation.
Superior Music - Fender Amp, Amplifier Serial Numbers Fender Amps FENDER Tube Amplifier / Amp / Serial Number, Date - Dating, Speaker code & Tube Information by; Chuck Kotlaris This data base is for use for dating and verifying your amp. This information is not for commercial use, and cannot be copied, posted, pasted or otherwise used in any publication or web site. Fender Tube amp codes: 1953-1970 - (look for a 2 letter code stamped on the tube chart inside the back of the amp)- the first letter is the year, and the second letter is the month.
An amp stamped NA would have been made in Jan. Here is a list of the first letter showing the year of manufacture. These codes have nothing to do with the serial number that is stamped on the right rear of the chassis - Those numbers are posted below. A=1951, B=1952, C=1953, D=1954, E=1955, F=1956, G=1957, H=1958, I=1959, J=1960, K=1961, L=1962, M=1963, N=1964, O=1965, P=1966, Q=1967, R=1968, S=1969, T=1970 A=Jan, B=Feb, C=Mar, D=Apr, E=May, F=Jun, G=Jul, H=Aug, I=Sep, J=Oct, K=Nov, & L=Dec. ' Pre-CBS' Blackface Amps are labeled 'Fender Electric Instruments'.
Student of the year wedding instrumental mp3 download. After CBS bought Fender in 1965, amps were labeled 'Fender Musical Instruments'. Early Fender Electric Blackface amps from 1964 and some into early 1965 did not have a Fender Logo on the grillcloth.
' Pre-CBS' Blackface Original Amp Knobs have the set screw at the number '10'. Fender Blackface amps & early Silverface amps used cloth covered wire until sometime in 1968. Silverface amps with aluminum trim surrounding the grill cloth are 1968 models Silverface Amps began in 1968, when Fender made circuit changes to most amps, making them a little less desirable than the blackface amps. A good amp tech can make these sound great. In 1973, Fender removed the 'Tail' from the logo.
A push-pull pot was added to some amps in 1974. Therefore, if you have a push-pull pot, your amp is 1974 or newer. 1970-1989 - Most amps do not have a date code stamped on the tube location chart. These codes are for amps with the serial number beginning with a letter: B+5-digits - 1975-1976 A6+5-digits - 1976 A7+5-digits - 1977 A8+5-digits - 1978 A9+5-digits - 1979 F0+5-digits - 1980 F1+5-digits - 1981 F2+5-digits - 1982/83 F3+5-digits - 1983/84 F4+5-digits - 1984/85 F9+5-digits - 1979-1980 EIA numbers taken from the transformers may help you to determine the date of production on amps that fall between the different dating schemes. These numbers always begin with '606', and are followed by three or four digits in various combinations.
If three digits are present, the first digit would refer to the year i.e. ('7' would mean 1967). If four digits are present, the first two digits refer to the year i.e. ('66' would mean 1966). The last two digits would refer to the week of the year i.e. ('26' would mean the 26th week or approximately June).
An example would be: EIA 606-4-21 would mean the 21st week of 1964. All Fender amplifiers, manufactured after 1989 include a date code on the amplifier. This code is located on the 'QA' (Quality Assurance) sticker, which may be found on the back of the amp chassis.
The sticker is a Black and Silver label, which contains several lines for 'sign-offs' at the completion of sound and electrical tests, where applicable. The last line will have 2 letters of the alphabet either printed or written by hand. Good luck reading some of the hand written ones.
These letters are the production date code for the amplifier. The first letter refers to the year, and the second letter refers to the month of manufacture. The codes are: 1990-A / 1991-B / 1992-C / 1993-D / 1994-E / 1995-F / 1996-G / 1997-H / 1998-I / 1999-J / 2000-K 2001-L / 2002-M / 2003-N / 2004-O / 2005-P / 2006-Q / 2007-R / 2008-S / 2009-T / 2010-U / 2011-V 2012-W / 2013-X / 2014-Y / 2015-Z FENDER AMP Chassis Serial Number DATE CODES These are the numbers you will find stamped into the chassis.
