Key Features
Keeley's dynamic processing expertise has allowed them to implement innovative features into their pedals. As such, the Compressor Plus is a compressor with an expander/sustainer on board. Not only does it deal with regular compression, limiting the peaks of your playing, it also adds more and more gain as your notes fade out. This added sustain can transform your sound completely, giving you rich, creamy tone that can last as long as you want it to. Gone are the days of notes and bends dying out prematurely, the Compressor Plus can bulk up your sound with the perfect amount of sustain and expressive bloom.
The Compressor Plus is equipped with a handy Release Switch designed to give you the perfect compression release settings for your instrument. With the ability to toggle between Single Coil and Humbucker release, you can easily transition between release settings depending on the guitar that you are using. Due to Humbuckers having more average energy than a Single Coil pickup, this can cause compressors to remain in "compression mode" for longer than they should, often resulting in dull, flat sounding notes. The Humbucker setting on the Release Switch gives you a quick release setting to combat this, giving just the right amount of release to sustain your sound perfectly, whilst keeping it from sounding off.
The Tone Control on the Compressor Plus is Keeley's very own design taken from analogue delays and other vintage effects units. The units it was taken from used an emphasis circuit in order to recover treble that had been lost when the signal went through a BBD or other analogue delay lines. That circuit has been taken and carefully crafted into a dynamic and complete tone control in the Compressor Plus, enabling you to maintain an astounding tone, even under heavy compression.
The Blend feature on the Compressor Plus is the ideal way to get peaks to come through and get sustain simultaneously. You can keep your peaks and transients by utilising the Blend and Tone Controls, and add sustain in the back end. Perfect for beefing up your sound and keeping it under control at the same time.
Keeley's Chief Engineer and founder, Robert Keeley, says that compression was the first effect he found that was hard to make sound good off the shelf. 15 years of development and experimentation have fixed that. Now down to a science, but still treated like art, Keeley's compression units are renowned the world over for achieving everything from heavy funk and chicken-picking sounds, all the way to smooth, subtle washes or complete ambient bliss. Perfect for use with other effects both correctively and creatively, you can achieve enormous walls of sound without having to spend a fortune on studio time. The Keeley Compressor Plus is studio-grade compression in a box.
