MXR M225 Sub Octave Bass Fuzz Effects Pedal

Unleash bone-crushing low end and searing synth-like grit with the MXR M225 Sub Octave Bass Fuzz. Designed specifically for bassists who demand huge tone without sacrificing fundamental clarity, the M225 combines two classic fuzz circuits with a dedicated sub-octave generator into a rugged, pedalboard-friendly unit.

Whether you need a vintage, warm harmonic growl, a razor-sharp modern fuzz bite, or floor-shaking bass synth textures, the M225 delivers versatile tone shaping that cuts through any mix while keeping your low frequencies tight and punchy.

Key Features

• Two Selectable Fuzz Voicings: Toggle between a warm, scooped vintage fuzz profile and a modern, high-gain fuzz circuit with aggressive midrange bite.

• Independent Sub-Octave Signal: Adds a clean, subterranean octave-down note to generate deep, monolithic tone reminiscent of vintage analog synths.

• Dedicated Clean & Fuzz Blend: Independent controls for Dry, Fuzz, and Sub Octave levels allow you to preserve your bass's natural attack and punch underneath layers of heavy saturation.

• Comprehensive Tone Sculpting: Tailor your fuzz voice precisely with dedicated Bass and Treble EQ controls to prevent low-end mud or shrill highs.

• Road-Ready Durability: Built into a heavy-duty MXR cast-aluminum enclosure equipped with true-bypass switching to keep your core signal completely uncolored when disengaged.
