Keeley Compressor Plus (Compressor/Expander/Sustainer)
They say:
The Keeley Compressor Plus is a compressor with an expander/sustainer. Not only does it act as a regular compressor, limiting the peaks in your playing, it adds more and more gain as notes fade out. Now you have sustain. Nothing worse than a note or a bend that has died before its time. The Keeley Compressor Plus adds just the right amount of sustain and expressive bloom to your notes.
The new Release Switch on the Keeley Compressor Plus is designed to make it very easy to transition between single coil and humbucker guitars. Humbuckers have more average energy than single coils which can cause compressors to stay in “compression mode” for a lot longer. When this happens, any series of notes you play will sound dull. With the quick release of the new Compressor Plus, your humbuckers remain true sounding, and each note retains dynamic attack and definition.
The Tone Control is our own design taken from analog delays and other vintage effects. Those effects used an emphasis circuit to recover treble and highs after they went through the BBD or other analog delay lines. We took that circuit and made it into a full fledged tone control! We have found that it is the perfect way to gently add back in those highs lost in the compression process.
