Considered by some the holy grail of Fender-designed amplifiers, the Twin Reverb was an 85-watt tone machine. Originally introduced in 1952, the Twin amp has undergone a number of revisions and circuit changes -- the Mojotone Twin Reverb style amp mirrors the AB763 circuit produced between 1963 and 1967. Throughout history, this amp has been used on countless recordings. To mention just a few, Mike Bloomfield, James Burton (guitarist for Elvis Presley, John Denver and Ricky Nelson), Kurt Cobain, Steve Howe, and even John Lennon and George Harrison all used Twin Reverb amps. These amps were responsible for some of the most iconic guitar sounds, and recordings ever produced.


The Mojotone Twin Reverb style amp is 85 watts of all-tube-driven class AB glory. It pairs well with two Mojotone Anthem 12" speakers. The combination of these two classic high-powered speakers and four 6L6GC power tubes gives the Mojotone Twin Reverb style amp a mountain of clean headroom, allowing users to run their favorite pedals through the amp at any given volume and still sound like an absolute pro. Thick and meaty low end fills out the character of the guitar tone while still exhibiting clear and pleasant highs that don’t pierce the listener’s ear. For those who want to feel the supreme ruling power of the Mojotone Twin Reverb style amp, there is an extension speaker output on the backpanel of the amp. As always, you can swap out the 12” speakers to those of lower power handling, to give the amp an earlier breakup and a throatier tone.

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 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.

Great Build…

by Marcie

Nice kit!!! Just be prepared for “old school”… Everything went together perfectly with the exception of the biasing network. Kit comes with a 27K resistor that is incapable of giving you the tolerances you need. Crazy thing is an extra 6.8K resistor was left over that I couldn’t find where it went in the kit. Well, that extra resistor is a perfect bias resistor!!! Was that intentional on Mojo’s part?!? No idea!!! But overall, a wonderful kit that is a fun build and gives you a beautiful clean toned amp!!
