Spires

EarthQuaker Devices packed two distinct fuzz circuits into the Spires. Red channel uses silicon transistors, Green channel uses op-amp square wave generation. The Red fuzz delivers classic silicon fuzz tones from light crunch to saturated sustain. The Green fuzz creates synth-like square wave fuzz with gated character. Either can run alone or they can stack. Two footswitches control each section. Stacking order puts Red into Green. Each has Volume, Fuzz, and Tone controls. True bypass via relay switching.
