Hybrid distortion fuzz with two-way tone and gain circuits modeled on the Boss DS-1 and EHX Big Muff. Allows you to use the Muff tone circuit with a DS-1 type gain circuit, or vice versa. (DS-1 moderate gain with Muff-style scoop near noon is particularly cool)
Brand new, played for maybe a few minutes, never left the home. Comes with the box & packaging.
