The Keeley Compressor is the award winning industry standard for stomp box compression. The 4 Knob adds Input Clipping and Attack controls to the top of the the original Keeley compressor for easy adjustment. Perfect for those that often switch live between single coils and humbuckers. The sound alone will inspire your creativity.

All of our Compressors are hand built in the USA. Unlike any other compressor, the Keeley Compressor was given the Editor’s Pick Award from Guitar Player’s Magazine and recently awarded Reader’s Choice for Stomp Box. It is a true audiophile and studio grade compressor with an exotic rack mount quality in a stomp box form.

The Keeley Compressor effect has nothing but tone tested components and true bypass switching and the effect switching incorporates a triple pole-double throw switch! The user will marvel at the clean unaffected sound when in the bypass mode and the compressor has an LED for effect indication.

Metal film resistors and capacitors ensure the cleanest compressor on the market. Hand matched transistors to less than 1% tolerance and ensures the musician receives a perfectly compressed signal with no chance for unwanted distortions.

The sound quality of the Keeley comp is unheard of in the stomp-box arena and is only seen in the high-end, very expensive rack-mount or tube equipment.

After tweaking the compressor design, the Keeley Compressors now have an input sensitivity control which allows the user to run keyboards, drum machines, drum mics, master recordings and other line-level uses with the Keeley Compressor. You’ll raise your signal to a new level of Sonic-Awesomeness.

The Keeley Compressors now have an Internal Attack control, designed for bass players with high output active pick-ups or active pedal boards with buffers.
