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.
