Compressor Pedal – Keeley 4 Knob Compressor

The Keeley 4 Knob Compressor is a studio-grade compressor in stompbox format, designed for guitarists who need dynamic control without affecting their core tone. Built in the USA, it has become a well-established tool in both live and studio settings.

Four Controls for Precise Tone Shaping

The pedal features four controls: Sustain, Level, Clipping, and Attack. The Sustain knob adjusts dynamics from subtle leveling to more pronounced compression for solos. The Attack is an internal control, primarily designed for bass players or those using active pickups. The Clipping (Input Sensitivity) control allows the pedal to be used with other sound sources such as keyboards or drum machines.

Versatile in Various Applications

Constructed with high-quality components, the Keeley 4 Knob Compressor is suitable for a wide range of uses—from home practice and recording to stage performance. It includes a clear LED indicator and true bypass switching, ensuring your guitar’s original signal remains unaffected when the pedal is off.

Power Supply and Construction

The pedal runs on a standard 9V DC adapter and has low power consumption. It is compatible with most common power supplies on the market.
