Keeley Oxblood Overdrive

Keeley · pedal

The Keeley Oxblood Overdrive is inspired by the Klon Centaur but built to deliver more gain than the original circuit, spanning a range from transparent boost to rich, harmonic overdrive. It uses a classic three-knob layout (Level, Tone, Drive) enhanced with a Phat switch for added bass presence and a Clipping switch toggling between uniquely voiced diode options, running on standard 9V DC power with true bypass switching.

  • “More available gain than a stock Klon-style circuit gives genuine extra headroom for pushing into heavier overdrive territory while retaining the touch-sensitive transparent character at lower settings”

    — from the reviews

  • “Primary use case is players wanting Klon-adjacent transparent boost and overdrive with more headroom to push into higher-gain territory when needed”

    — from the community notes

  • “Clipping switch for alternate diode voicings adds meaningful tonal variety beyond the classic fixed Centaur clipping structure”
