Black Box Booster

The BSM Treble Booster is a high-gain treble booster and preamp designed to enhance the sound of electric guitars, particularly when used with medium humbucker pickups, P90s, and single coils. This pedal is tailored to push the high treble input of British-style tube amplifiers, such as Plexi models, producing a powerful sound. Musically, the Treble Booster delivers a rich, cutting tone that can be driven into saturation, offering flexibility in dynamic playing. While it operates at 18 volts for maximum performance, it functions well at 9 volts with slightly reduced intensity. The pedal includes a status LED and features a low-noise preamp stage followed by a high-gain silicon output for versatile tonal shaping.
