Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squash, sustain, and sparkle that made it a go-to for guitarists. Simple 4-knob control layout lets you dial in Level, Sustain, Attack, and Clipping/Blend-style tone shaping for everything from subtle leveling to punchy country snap. Built in a rugged metal enclosure with standard 1/4" input/output and 9V DC power for easy pedalboard integration.
