Next-Level Compression Made Simple
The Compressor Plus introduces intuitive features like a Release Switch, specifically voiced for either single coils or humbuckers — no more guesswork. Just flip it, and your guitar responds exactly how it should.

Humbuckers get all the attack and energy they need, while single coils remain articulate and chimey. Whether you’re dialling in country twang or ambient shimmer, this pedal adapts to your playing style and guitar instantly.

Tone Control with Vintage Soul
Inspired by analog delay circuits, the custom Tone Control brings clarity and sparkle back to your sound — perfectly balancing what compression often takes away. Smooth out the edges without losing the magic.

Blend In the Best of Both Worlds
With the Blend knob, you keep your natural attack and transients while adding just the right amount of sustain. It’s the perfect solution for players who want control without squashing their dynamics. Think of it as “Manhattan Compression” made easy — subtle, musical, and completely in your hands.

More Than a Compressor
The Compressor Plus is a tone sculptor, a boost pedal, a sustain machine, and an essential looping tool. Whether you’re going for clean ambient textures, stacking it with fuzz for massive walls of sound, or using it to tighten up your rhythm work, this pedal does it all — and makes it sound amazing.

Crafted with Passion. Built to Last.
Designed and built in Edmond, Oklahoma, the Compressor Plus represents over 15 years of dedication to mastering the art of compression. Founder Robert Keeley took on the challenge of making a compressor that feels alive — and nailed it.

Whether you’re in the studio, on stage, or jamming at home — the Keeley Compressor Plus brings your tone to life.
