Detail 01
Custom multi-tapped output transformer
Its toggle selects between different transformer windings for BOLD or RICH operation.

Independent shopping perspective
Supro Drive is an analog guitar overdrive pedal built around a circuit intended to reproduce the complete Supro amp path, including an output transformer. Its straightforward Volume, Gain, and Tone controls make the main adjustment familiar, while the transformer-winding toggle moves between the higher-headroom BOLD setting and the more compressed, higher-gain RICH setting. A TRS expression connection can vary Gain, letting you set an upper limit on the pedal and define its lower limit internally.
