The Muff Sound is based on the early ‘Rams Head’ Muff fuzz with the addition of a variable ‘Mid’ control, using the same distinctive model transistors used in the original to reproduce the lower compression characteristic of this pedal. Unlike the typical hugely scooped tone associated with the Big Muff circuit, the original Rams Head intentionally filtered out low end frequencies that caused the sound to become muddy and had lower gain values than typical of modern circuits. Although our Muff Sound is still capable of very high gain, the transistors used in this variation of the circuit offer slightly less compression and a more open sound. The result is subtle but gives the Muff Sound its own character, especially when used with lower gain settings and boosted with other pedals before or after the fuzz unit. Alongside this lower compression, the addition of the Mid control also gives you more control over your tone, and together reduces the risk of disappearing in the context of a full band (always a risk with more scooped Muff circuits).
