This is what a muff is! My favorite version of the Triangle era fuzzes.
The biggest, meanest, grittiest and smoothest sounding Triangle.
Monstrous fuzz with a throaty, wooly, gritty break-up on the lower notes and a sweet, full, blooming, smooth fuzz on leads. The tone of the pedal is balanced with a little extra low end throughout that gives it a meaty fullness.
