Doheny Audio "The Monarch Module" Overdrive / Boost Guitar Pedal

A refined JFET circuit blended with germanium character.

Voiced entirely by ear.
Released in limited numbers.
Built once.

Designed to capture the warm, gritty edge of a tube amplifier at its threshold—delivering natural breakup, harmonic richness, and controlled crunch at practical volumes.

A dedicated voice switch lets you choose between Vintage (Warm) and Modern (Bright) tones, making it easy to shape your sound on the fly.

Roll back your guitar’s volume and the circuit cleans up into a dynamic boost, adding clarity and presence without losing character.

Each unit is hand-assembled and individually calibrated in Salzburg.
