KEELEY 4 KNOB COMPRESSOR – VINTAGE GUITAR COMPRESSION

All of our 44,000+ of our Keeley 4 Knob Compressors have been built in the USA.  It’s been at home on stages, the studio, churches, as well as bars and bedrooms!  The Keeley Compressor was given the Editor’s Pick Award from Guitar Player’s Magazine and recently awarded Reader’s Choice for Stomp Box Compression.

From my original website in 2001… “It is a true audiophile and studio grade compressor with an exotic rack mount quality in a stomp box form. The sound will inspire your creativity.

The Keeley 4 Knob Compressor 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.

The sound quality of the Keeley 4 Knob Compressor is unheard of in the stomp-box arena and is only seen in the high-end, very expensive rack-mount or tube equipment.”

Standard 9V DC battery and AC adapter connection. Low Current Draw – 5mA.
