These custom "tone machines" will get you and your fans rockin' !  They were inspired by the classic 50's-60's tube amp designs that create the "tones you know and love" plus they have many added features and custom options not found in the original vintage amps which allows you to create your own design and your own individual tones! All have custom dual voiced preamps with separate gain controls. The combination of voice, gains, and tone stack settings is almost unlimited...plus you can use different types of preamp and output tubes and choose solid-state or tube rectifiers...plus  a passive buffered effects loop! Think of these amps as the ultimate weapons for the serious creative player. All the amps are full frequency range amps and work great with guitar, bass, keyboard and harp.
