TBO-9 True Tube Booster/Overdrive

BOOSTER

OVERDRIVE

The TBO-9 combines Clean Boost and Overdrive capabilities with a tube gain stage to create a versatile tone-shaping tool. The ideal complement to non-master volume tube amps, the TBO allows you to drive a clean or semi-clean amp to the breaking point, giving it that “on 10” tonality at a much lower volume level and without altering the amp’s signature tone. The TBO-9’s tube stage is controlled by the Boost knob which adds a fat, warm bottom end with a slight mid bump as it increases the output level. The Drive knob blends clean and distorted signals, allowing the user to dial in a small amount of grit with minimal coloration.
