One Knob Fuzz

The Doheny Audio One Knob strips the legendary Big Muff Pi down to its purest form—just one gain stage delivering smooth, low-gain fuzz that transforms into a warm boost when you roll back your guitar’s volume.

At the core is a hand-selected NOS silicon transistor, chosen for its bold, vintage character. Carefully tuned diodes deliver warm, dynamic clipping that balances grit with clarity. The single volume knob does more than set input—it acts as a sustain control, pushing your signal into bloom or backing off for cleaner tones. Flip the switch to explore different frequency voicings, adding flexibility and feel to your tone.

Features:

• One-Knob Simplicity – Go from clean to mean with a single control that also shapes sustain.

• Frequency Toggle Switch – Selects between two tonal characters for added versatility.

• True Bypass Switching – Preserves your clean tone when the effect is off.

• Standard 9V DC Power – Compatible with any standard 9V center-negative supply (not included).

• Handmade in Los Angeles – Boutique tone, built with care.

• Limited Release – Only 3 units available in this batch.
