Ace Octave Fuzz

The Wren and Cuff Ace Octave Fuzz is a meticulous recreation of the vintage Acetone FM-2 Professional, delivering bold fuzz with a pronounced, clear octave-up effect—especially noticeable above the 12th fret. Distinct from other classic octave fuzz designs, it offers a unique tonal character with rich saturation and strong note definition. A Tone toggle switch lets you choose between a more mid-focused voice or a thicker, low-end-heavy response for added girth and depth. Developed using carefully studied vintage units rather than relying solely on schematics, the Ace Octave Fuzz captures the authentic feel and response of the original circuit. With its aggressive edge and expressive octave texture, it’s a distinctive fuzz that brings character and inspiration to any pedalboard.
