Used Keeley 4 Knob Compressor Effect Pedal

Smooth out your tone with this used Keeley 4 Knob Compressor in good condition, a studio-style compressor that adds sustain, clarity, and punch without sacrificing feel.

Built in a rugged stompbox enclosure with standard 1/4" input/output jacks and 9V DC power operation.
