Keeley 4 Knob Compressor Review

Keeley 4 Knob Compressor Review FAQ

How does the keeley compressor plus work?

Keeley Compression is how. The Keeley Compressor Plus is the first true advancement in our 2 and 4 knob compressor line. The new features are simple and straight forward. Now there is a simple Release Switch that is tuned for single coils or humbuckers. No more wondering if you have the attack or release set right.

What kind of power does the keeley keeley plus use?

It runs on standard 9V power, and there’s a battery compartment. Like most of Keeley’s compressors, the Plus is based on the 1970s Ross Compressor, which was itself a near-clone of the earlier MXR Dyna-Comp. (Really. I’ve got schematics for the Ross and MXR right here, and the “two” circuits are very similar.)

How many compressor pedals has robert keeley sold?

Oklahoma’s Robert Keeley Electronics has actually sold nearly 50,000 U.S.-made compressor pedals—a remarkable figure for an indie builder.

How many knobs does the compressor plus have?

Both pedals had just two knobs (compression amount and volume), where many full-featured studio compressors enabled control of compression ratio, attack and release times, and more. The Compressor Plus remains a simple ’70s-style stompbox squeezer at heart.
