Wren and Cuff Ace Octave Fuzz Recreating the awesome fuzz tone of the old "Acetone FM-2," the Ace Octave Fuzz provides bold, rich fuzz with a very precise octave-up. A much different pedal than the Tycobrahe Octavia or Univox Superfuzz, this pedal has a tone that is unique among octave fuzzers. The Tone toggle switch provides the option of a more mid-range focused sound, or a fat girthy sound with tons of extra lows. We actually used vintage units, removed parts, and attempted to replicate the tone of a pedal that has been used for many years. The Wren and Cuff Ace Octave Fuzz will be a unique addition to your board that will inspire your playing with its raunchy goodness.
