The Teisco Boost is a FET-based boost and buffer modeled after a classic vintage preamp. Soft, organic clipping from the field-effect transistor, a 9V/24V voltage switch for extra headroom, and an EQ profile switch make it useful as a clean push into an amp or drive, or as a tone-shaping buffer at the start or end of a board. Controls Level and Gain set output and drive into the FET. The voltage switch selects 9V or internal 24V operation for more headroom. An EQ profile switch and Buffer control tailor the voicing for different amps and pedal chains.
