Description

The Supro Boost Pedal is a high-headroom JFET clean boost designed to push the front end of tube amplifiers into rich harmonic saturation without altering your core tone. Delivering up to 20dB of noiseless gain, it excels at enhancing sustain, touch sensitivity, and dynamic response—perfect for solos, tone shaping, or driving vintage-style amps harder.

A Dark/Bright toggle provides flexible tone shaping via high-pass and low-pass filtering, allowing you to tighten humbuckers or add body to single-coils for better placement in a mix. The inclusion of a TRS expression pedal input enables real-time control over gain, making it easy to swell into leads or fine-tune boost levels on the fly.
