Base pedal: D*A*M FS-77
Based on the D*A*M FS-77, a hand-built boutique fuzz from David Main's revered British workshop — circuits that routinely sell for hundreds and are notoriously hard to source. The FS-77 delivers a thick, vintage silicon fuzz character with that distinctive D*A*M focus and sustain. Building one is essentially the only practical way most players will ever get to run this circuit.
