Mojotone’s Tweed Twin High Power Style Amp Kit is a faithful recreation of what many consider the holy grail of guitar amps. Ringing in at 80 Watts of glorious tube power, our TTHP delivers the famous tones produced by timeless artists such as Stevie Ray Vaughan and Keith Richards. This amp is ready for the main stage, and fits into any mix perfectly without being too harsh or too muddy. Pair this Twin with a Stratocaster to mimic that rocking Buddy Holly or Tommy Allsup sound without feeding back.


Leo Fender took the tone stack from the beloved 5F6-A Bassman and dropped it into this high-powered tone monster. Using the same selection high-quality small components as all of Mojotone’s amps, this particular circuit calls for a quad of 6L6GC power tubes that keep the amp cleaner at higher volumes and reproduces every part of the sonic spectrum appropriately. Two Anthem 12" 50 Watt speakers give the amp a smooth and straight-forward tone with high frequency chime.


Unlike its lower powered counterpart, the TTHP has a middle control for further contouring; this makes the amp's global controls presence, middle, bass, and treble. There are two channels, bright and normal, and each has two inputs. The normal channel is more tame with a slightly warmer overall sound, while the bright channel has a more aggressive sound and breaks up slightly faster. These inputs can not only be used in a traditional fashion but can also be ‘jumpered’ together and blended, via their dedicated volume controls, for even more sound options.

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.
