Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic Keeley sustain and sparkle for guitar or bass. Four intuitive controls—Sustain, Level, Attack, and Clipping—let you dial in anything from subtle smoothing to punchy, squashed compression. Built in a rugged, compact stompbox enclosure with standard 1/4" input/output and 9V DC center-negative power, it’s a studio-quality compressor that’s easy to use on any pedalboard.
