Keeley Electronics is a company widely known for the quality of the pedals that they're putting out. And the Compressor Plus is a great example, with its premium build quality and tone, combined with player friendly controls.

It boasts hand-matched transistors to less than 1% tolerance, and uses quality metal film resistors and capacitors.

The blend knob lets you mix your dry signal with the compressed signal, which can be useful for adding back dynamics as you see fit.

The pedal can also be quickly tweaked via a switch to be compatible with single coil and humbucker pickups, a very useful feature that makes this pedal easier to integrate into rigs.

Other controls include level, sustain and attack, all of which are straightforward.


  • JFET compression
  • Parameters: Sustain, Level, Blend, Tone, Pickup Type Switch
  • True Bypass
  • 9-Volt Battery or AC Adapter


Most users of this pedal agree that sound quality is top notch, often described as detailed and clean. Versatility is another one of its strengths, reportedly working with various single-coil and humbucker equipped guitars from Fender, PRS, Gibson and more. It is also often commended for its overall build quality.


Being clean sounding can be a detriment for those looking for more power and sustain from their compressor pedal.


If you're looking for an affordable yet good quality compressor that'll easily adapt to your rig, then the versatility of the Keeley Compressor Plus will be a great match especially for those with multiple guitars.
