Blackface Princeton Reverb® Style Guitar Tube Amp Kit

The Blackface Princeton Reverb® Style Guitar Tube Amp Kit delivers one of the most iconic Fender-era tones in a compact, studio- and gig-ready format. First introduced in 1964, the Princeton Reverb quickly became a staple in guitar history, prized for its shimmering clean tones, lush long-spring reverb, and tube-driven tremolo.

Inspired by the legendary AA1164 circuit, this amp builds on the foundation of the Tweed Princeton while adding the signature Blackface enhancements players love. The result is a versatile, articulate amplifier that excels in recording environments, small venues, and home studios alike. Over the decades, the Princeton Reverb sound has found its way into the rigs of countless professional guitarists, becoming a benchmark for classic American tube tone.

The Mojotone Princeton Reverb style amp kit produces 12–15 watts of rich, harmonically complex power and pairs beautifully with our Anthem Series 10" 35-watt speaker. Like original Blackface Princetons, this design includes an added gain stage after the reverb circuit, allowing the amp to push into thicker saturation when driven. Combined with the smooth compression of 6V6 power tubes, the result is a creamy, soulful tone with exceptional touch sensitivity and character.

This amp features one channel with two inputs.

-Input 1 delivers a slightly hotter signal, ideal for single-coil pickups.

-Input 2 is more mellow, making it perfect for humbuckers.

This thoughtful design lets you switch guitars without constantly adjusting volume levels.

The straightforward control layout—Volume, Treble, Bass, Reverb, Speed, and Intensity—provides everything you need to dial in classic Blackface tones without unnecessary complexity. From sparkling cleans to warm breakup, this amp handles pedals exceptionally well and adapts to nearly any musical setting.

Disclaimer: Some of the parts contained in this kit are subject to availability.

Mojotone reserves the right to change or substitute any and all of the parts contained in this amplifier kit without advertisement or notification to the buyer. Part substitutions made by Mojotone are guaranteed not to affect the integrity or operation of your amplifier kit. Time estimates listed are from start to finish. If you are new to tube amplifiers, additional time may need to be factored.

 When purchasing a kit from Mojotone, you will receive the following documentation.

1. Schematic

2. Wiring Diagram / Layout

If you purchase a kit from Mojotone and do not receive these documents, you can obtain copies by emailing tech@mojotone.com or calling 800-927-6656. The Mojotone staff is available Monday through Friday from 8:30 a.m. to 5:00 p.m. EST unless otherwise closed.

 Mojotone kits include the best quality parts that are available at the time of purchase. If a substitution is required, our team will use parts that are of equal quality to ensure the integrity of the kit build remains the same.

Building a fully functional amplifier kit is not an easy task. Before building a kit, one should have the ability to properly solder as well as read and understand a schematic and wiring diagram. While we do our very best to ensure all documentation is current, the included documentation is meant to serve as an overall guide to building the amplifier. Simply following the schematic and wiring diagram does not guarantee you will have a fully functional amplifier. In fact, post build troubleshooting is a common issue across all builds.

Our staff is available to assist with basic troubleshooting needs. There are plenty of online videos available that are helpful with most post build issues. Technical staff is available via email by sending a message to tech@mojotone.com. You may also call our sales team to discuss build problems, dial 800-927-6656 and press 1 for sales.

 Building a tube amplifier takes time, dedication, resources and most importantly... Skills! The experience of building an amp can come with some frustration, the reward of completing the build is definitely well worth your time. Please review the wiring diagram, schematic and manual (if applicable) prior to making your purchase. Mojotone will not accept any returns on amplifier kits and/or parts that have been assembled, soldered or modified.

Reviews

Awesome kit

"This kits had everything needed to build a Princeton Reverb. It was fun to build, went together without a single hitch, and sounds great! Thanks everyone at Mojo!"

— Charles W. (5/5)

Very Happy with Blackface Princeton Kit

"The kit does require some attention to detail but there was no troubling difficult steps in the process. I had a lot of fun building this kit. Now I'm looking for what other kits I might try and build."

— David 2. (5/5)

I am very happy with

"I am very happy with the kit. The instructions were excellent and the final result is great looking and great sounding! So much fun I have subsequently purchased and completed the Mojotone Deluxe Reverb."

— Dwight C. (5/5)

Princeton is a work of art

"It took about a month to assemble every Saturday, Sunday and weekday night. I am satisfied with the low noise, warm tone, and rich low temperature. I have a deluxe reverb on a PCB, but this Princeton is less noisy and richer in bass than a deluxe reverb. If the deluxe reverb of a PCB is an industrial product, this Princeton is a work of art. This Princeton is an amp that brings out the full performance of your guitar. Even the smallest sound is output. I ordered it from Japan and it cost $ 350 for the fare, but I'm still very happy with the sound."

— Rod (5/5)

A Classic Amp For My First Amp Build

"Years ago I played an old 60's Princeton Reverb at a local recording studio and it was one of the greatest sounding amps I've ever played. It always left an impression on me, so when it came to my first amp build and I found out mojotone had a kit for it, I knew I had to build it. This went very well thanks to the assembly manual and the included schematic and wiring diagram. The amp sounds amazing, and I'm already anxious to build another guitar amp."

— Gary A. (5/5)

A great kit that will make a great amp

"A very well put together kit, with good instructions and nice parts. I really like the mojo branded CTS pots - nice touch! I forgot what a joy cloth pull-back wire was to work with. The final result was a well-sorted Princeton that is very quiet and sounds great at all volume levels. I built this amp for myself, but I would build it for a client without any worries that it would fail - even under typical touring conditions. I did some minor changes (installed a bias control, screen resistors, and grid stoppers), which I would recommend for any Princeton. Take your time and check things as you go, and you'll have a great amp at the end of it. And remember kids, probe with one hand!"

— Toshibumi (5/5)

The Best Princeton Kit Around

"Excellent kit. Shipped with no damage and with all of the required parts and some extra. Fender charges around twice the cost for a similar, point to point wired amp so this is an absolute bargain (and satisfying to assemble). The eyelet board design is easy to work on (and modify if you want to tailor it to create your own sound), the instructions are simple and easy to understand. The sound is lovely clean and sweet Princeton sound you would expect from an expensive fender. The support team was polite, responsive and very helpful. Would highly recommend this product."

— Aaron (5/5)

Best instructions kit!

"There are a number of decent Princeton Reverb kits out there, but my son was a first time kit builder so DETAILED drawings and step by step instructions really helped out and made sure that as soon as we flipped the power switch, it all worked. This is the way to go."

— Kevin N. (5/5)

Princeton Reverb Style Tube Amp Kit

"This is a very good kit with high quality components! Even though I retired from 42 years of Electronics Experience at DFW Airport I found the large color diagram extremely useful. In fact it allowed my old brain to somewhat cruise as it shows each component’s location and routing of the wiring. I enjoyed this build and when complete works nicely! I used the instructions for when to install and methods needed. The large schematic is easy enough for these 72 year old eyes to see. Thank you Mojotone for making this kit easier, fun, and a joy to use! I highly recommend buying their wooden amp chassis holder as it made things a lot easier. You could make your own but theirs is well thought-out and easy to adjust to different size amp chassis."

— David P. (5/5)

I knew it be good but wow!

"This was my 4th kit build from Mojotone I upgraded some of the caps to Jupiter and a Soursound output transformer, the amp just blows me away really quiet and just sounds fantastic, currently its running through 2-12 jensens. Take your time and you'll have one great amp."

— Chris (5/5)
