With its signature crunch and mids-forward bark, the Big Muff 2 is a take on the long-lost Op-Amp Big Muff Pi circuit from the 1970s. We’ve added two of our favorite features to expand its tonal capabilities in the Big Muff Pi 2 with Tone Wicker. Expanded top-end and a full-range fuzz make for even more unique muff tones.
