The Keeley Compressor Plus is not just a compressor; it's also an expander/sustainer. It functions as a standard compressor, taming the peaks in your playing, while progressively adding gain as the notes diminish, providing sustain. There's nothing more disappointing than a note or bend that fades too soon. The Keeley Compressor Plus ensures the right amount of sustain and adds an expressive bloom to your notes.

The innovative Release Switch on the Keeley Compressor Plus facilitates seamless transitions between single-coil and humbucker guitars. Humbuckers, which have a higher average energy output than single coils, can cause compressors to remain in "compression mode" much longer, resulting in a muted series of notes. The quick release feature of the Compressor Plus ensures that humbuckers sound authentic, preserving the dynamic attack and clarity of each note.

The Keeley Compressor has become the world's most sought-after boutique compressor. Having constructed over 132,000 units as of February 7, 2024, our workshop possesses profound expertise in compression, limiting, and sustain.
