Forest for the Trees

Big Muff-style circuit designated BM20-Ultra with 23 adjustable circuit points via DIP switches, allowing millions of possible unique voicings. Can switch between germanium and silicon transistors and bypass the tone section entirely. 100% analog throughout.

Standard Big Muff knobs for Volume, Tone, and Sustain, plus 23 DIP switch adjustment points that modify circuit behavior at various nodes. The switches alter gain staging, clipping characteristics, and frequency response, producing everything from Muff sounds to overdrive, boost, and beyond.

Originally called the De La Riva. Inspired by DIP switches found on analog amp modelers. Essentially a Big Muff laboratory for players who want to explore every possible variation of the topology. True hardwire bypass, 8mA draw, 3.7 x 4.7 x 1.6 inches, 13 oz.
