JAM Pedals Red Muck is a fuzz-distortion pedal inspired by classic Muff and Russian fuzz circuits, delivering rich, saturated tones with a warm low end and smooth sustain. This used unit is in good condition, showing some cosmetic wear but fully functional. Featuring Volume, Tone, and Gain controls, it offers a versatile range from smooth fuzz to aggressive distortion, perfect for rock, blues, and stoner sounds. Housed in a sturdy, hand-painted enclosure, it runs on a standard 9V DC power supply. Whether dialing in thick, vintage fuzz or heavier modern distortion, the Red Muck delivers dynamic, amp-like response.
