Supro Boost

Supro Boost is a J-FET based pedal that delivers up to 20dB of noiseless gain boost plus optional treble cut or bass cut to contour your sound. The Supro Boost pedal sports a simple control layout with a single Volume knob and an oversized toggle switch to select BRIGHT, FLAT of DARK overall frequency response. The BRIGHT mode enables a 6 dB / octave HP (high pass) filter for thinning out humbucker guitars when adding boost to increase sparkle and prevent mud. The DARK mode enables a 6 dB / octave LP (low pass) filter for fattening up single coil guitars when adding boost to increase warmth and prevent harshness. Taking the boost pedal one step further, the Supro Boost offers a TRS port for expression pedal control of the VOLUME knob.
