Boost
Clean JFET-based boost delivering up to 20dB of transparent gain with three-position tone switch and expression pedal control.
The Supro 1303 Boost is a straightforward yet versatile clean boost pedal designed to remain sweet and transparent at all settings. Utilizing JFET-based circuit, provides up to 20dB of clean gain while maintaining exceptional clarity and headroom. Simple control layout features single Volume knob alongside oversized three-position toggle switch selecting between BRIGHT, FLAT, or DARK frequency responses.
BRIGHT mode enables 6dB/octave high-pass filter that thins out humbucker-equipped guitars when adding boost, while DARK mode provides 6dB/octave low-pass filter that fattens up single-coil guitars. FLAT mode maintains neutral frequency response. Unique feature is TRS expression pedal port allowing real-time control of volume parameter—on-board Volume knob sets maximum value while internal trimmer adjusts minimum.
Like all Supro pedals, assembled in Port Jefferson, New York, featuring custom-tooled, anodized, brushed-aluminum enclosures and true bypass switching. Accepts 9-18VDC power for maximum flexibility.
