'66 D-Reverb 22W Amp Kit

About This Item

Famously clean, with enough guts to gig
Perfect for recording and performing, the D-Reverb produces warm clarity that absolutely refuses to get lost in the mix.

One of the most popular amps ever built, the original AB763 circuit puts this amp in the happy middle between bright clarity and rich distortion. It excels in the studio and on the stage. While capable of crystal clear tones at good volume, you can push this beloved classic into beautifully saturated, touch-sensitive distortion. It's all here: clarity, distortion, and rectifier tube sag.

From the twangy tones of Elvis to the speed and articulation of Eric Johnson
For an example of what this amp can do, just listen to the tones of James Burton, Eric Johnson, and Jason Isbell. You'll hear its unmistakable tone driving the country rock Tele® sounds of Elvis's hits. Eric Johnson uses two of these amps live for smaller venues to achieve his expansive stereo clean tone. Jason Isbell loves this amp so much that you can hear it all over his Instagram.

StewMac has painstakingly recreated this timeless amplifier in our '66 D-Reverb 22W Amp Kit. This is one of our Icon Kits: loving reproductions of vintage classics.

If building such an iconic classic sounds hard, don't worry. We've gone to great lengths to make sure this kit has the best step-by-step directions in the industry. The '66 D-Reverb is a perfect place to get serious about amp building. It comes with all the parts you need to complete this project in just a few weekends.

Superb sound!


Verified Buyer

Had a blast putting the amp together, but had a minor issue; I'll take 50 % of the blame, but please (SM)add to the printed instructions at step 13 the info from the enlarged rectangle about joining one of the 3 lug grounding strip together. This omission led to numerous emails between (tech)Tommy S. and myself. Tommy was nothing short of spectacular going through items to check before nailing the aforementioned grounding strip issue. His patience was over the top, and his ability to reign in my frustration level puts therapists to shame. The end result was what is aptly named " the desert island amp". Kudos to Tommy and Stew Mac for reproducing this retro amp for purists to enjoy!


Delightful sounding amp


Verified Buyer

This was my first amp build, although I've had soldering experience working on guitars. It is a lovely sounding amplifier with a gorgeous fender clean tone and deep reverb.

As other reviewers have written the layout of the capacitors, resistors, and pots is very clear, and made taking inventory painless. And the instructions are clear and intuitive.

I only have two complaints. First, there isn't enough yellow wire to complete the build.
Second, the transformer included with the kit has more striped black wires than the one shown in the instructions. I found out from the mojotone website that the extra wires are taps for different voltages. Use the white and solid black wires for 120V US, and seal off the remaining wires with heat shrink or electrical tape. Stew Mac would do well to note this in the instructions.

Overall, I'm very happy with this kit, had a great time building, and love playing this amp.


Great company


Verified Buyer

This amplifier kit is so much fun to put together. The instructions included with kit makes it almost impossible to make a mistake. If you follow them and take your time you will have a great time building your amp. Thanks Bill D.


Great kit and a versatile amp!


Verified Buyer

This was the second amplifier kit that I have purchased and built. The first one was the 81 Brit 800; so I was familiar with what to expect. The kit was well packaged and no parts were missing. The only issues with parts were some stripped out control knobs and a defective pilot light bulb. I also ran short of yellow wire but substituted some wire I had left over from the previous build. Service rep, Matt is always eager to help and sent out the replacement parts I needed. The instructions are well written and easy to follow but I would personally like to see actual close-up photographs and a behind the main board diagram of all the jumpers would be helpful.
The amp worked first time and sounds like a Fender Reverb Deluxe should. The cleans are amazing and the reverb and vibrato are perfect. I have noticed an issue with the amp clipping on the Vibrato channel when the volume is past 5-6 and am waiting on a response from Matt on what it may be. I'm sure it will be an easy fix but that is why I am giving this a 4 out of 5 star review.
Overall; in my opinion, this kit is the most difficult amp to build that StewMac offers. I have soldered on both the turret style and eyelet style boards now and I think the eyelet boards are easier to work with. If you are detailed oriented, patient and can follow instructions, then you can build this amp and save yourself a ton of money.


Great kit and excellent instructions


Verified Buyer

Let me first state that I have built a number of Marshall and Fender clones. Those I generally ordered the parts from a number of different places to get all parts needed to build an amp. For example, one of three places I would order my American made transformers, another place the board materials, another place electrical components/wiring, and generally from Mojotone their chassis/cabinets. Normally I just had a number of schematics/layouts to work with and did my research ahead of time knowing what I needed and some important test points. In other words a lot of planning ahead of time and had to learn some things the hard way. I learned a lot that way!

When I started I knew absolutely nothing about amps/electronics and did not even know how to use a DMM or even how to solder. I looked around for something like what StewMac is now offering as far as build instructions but did not see anything like this. This is where I wish I could have started! The instructions are clear and very detailed, and while I prefer to work with a layout and have my own build sequence, they will step you through each task thoroughly.

Besides the steps for assembling the amp there is a nice section there in testing, measuring critical paths, and setting bias. And that includes a very critical section on how to work safely as you can injure or kill yourself if you do not follow recommended safety procedures like draining the filter caps.

For any new builder this is a great way to learn and you have knowledge backing the product being sold for any questions or issues you might have building an amp kit from StewMac. Even if I have some amp builds under my belt it was a warm feeling knowing if I had some kind of issue come up Matt & StewMac were available.

StewMac was responsive for anything I needed like shortage of wire, a grungy looking cap can that they replaced, or any missing parts shipped out promptly.

The parts are excellent and the transformers are made in the USA by Heyboer. The cabinet is pre-drilled which can save you lots of time or any miscalculation in fitting the chassis. The resistors are mostly carbon comp like originals from back in the day. The fiberboard is excellent to work with and no loose fitting eyelets.

If you take your time and follow the instructions you will get an absolutely stunning amp with reverb that is to die for. I now understand why this amp is one of the most beloved amps in history it is that good.

I highly recommend any of StewMac's amp kits there is quality and backing in those products.


Looking Forward to This One!


Verified Buyer

OK, maybe I'm jumping the gun a bit. Be that as it may, I am really looking forward to this build. I ordered this new kit this morning and it should arrive next Monday. I recently finished the 59 Tweed kit and for a first time kit builder I am quite pleased with the results. The "59" went together quite nicely, is an incredible sounding amp and worked fine immediately upon plugging it in for the first time,

So now I'm convinced that I can do it again with the 66 D-Reverb. While I am confident I can repeat my success I have to give credit where credit is due and that goes to Stew Mac for several reasons. One, the kit consists of great quality parts and Two, the manual is incredibly well done, easy to understand and if followed step by step your success is virtually guaranteed. I learned a lot from my first experience. There were, of course, a few minor issues with the Tweed amp but with some help from Matt at Stew Mac the issues wer quickly resolved.

That being said, I can't wait to get after this new and exciting challenge, It should be a great way to spend my free time and the rewards will be the sense of accomplishment and the awesome tone potential. It should be great fun.

I will, of course, do a follow up review when the project is complete.


This is a great amplifier!


Verified Buyer

I was unsure about my ability to build this kit. Like other StewMac kit builders/reviewers, I've never built an amplifier kit and have minimal experience with electronics. I can identify some components in a schematic and I can read a multimeter. To be successful, I'd have to rely solely on the instructions. Many other kit reviewers spoke about the quality of the kits, the support from StewMac and the clear, concise, step-by-step instructions. I concur with all those comments and they apply to the "66 D-Reverb kit, too.

The kit arrived well packaged and in god condition. I especially like that the small parts are organized in plastic, compartmented boxes. It made the inventory easy and, kept small parts from getting lost on my workbench. My kit was missing the eight 220K resistors. A call to StewMac customer service and they sent them out the next day. Great customer service.

It took me several days to complete the kit, in part because I took my time, read through the instructions several times and triple-checked each and every step of my work. After finishing the build, I followed the start-up instructions, precisely as outlined in the instructions and the amplifier worked exactly as designed. It's hard to describe how good it felt when I plugged my guitar into this amplifier and heard how great it sounds! It's a very, very quiet amp and has that Fender tone that I was hoping for. I was not disappointed at all and, I learned a lot about how my amp works!

*High quality components.
*Well organized parts, including pictures that make parts identification easy and ensure you're installing the correct component in the right place. Pay attention.
*Very detailed, thorough, step by step instructions with pictures, drawings, do's and don'ts.

*I needed more yellow, black and white wire. Partly because of older hands.
*StewMac needs to include a drawing of the back side of the completed main eyelet board that shows all the back side wiring. You can see the wires on the back side but, only in an "ghosted" view.

*Take your time and follow the instructions, step by step. Triple check your work and it may save a lot of headaches later.
*When the instructions say "don't do something now", don't.
*Use a good, sharp pencil to number and letter the eyelet boards. You need to be able to clearly see these numbers and letters throughout your build and that get's a lot harder as you add more and more components to the main eyelet board. If I were doing this again, I might number the back of the main eyelet board, too. But if you do, make sure you get the numbering right!

Finally, if I can build this kit, you can build this kit. The instructions are thorough, comprehensive and complete and it's clear that StewMac put a lot of effort into the instructions, with an eye towards making the build possible and successful. I'm going to build one of their other kits and just need to decide which one.
