Compressor Plus

The Keeley Compressor Plus is an analog compressor/sustainer designed to provide smooth compression while preserving the natural dynamics of the instrument. In addition to the standard Level, Sustain, and Blend controls, it features a Tone control to restore high frequencies that can be reduced during compression, and a Single Coil/Humbucker Release switch that optimizes the release time for different pickup types. The Blend control mixes the dry and compressed signals to retain picking attack while adding sustain. Designed for guitar but suitable for a variety of instruments, the Compressor Plus can be used for subtle dynamic control, sustained lead tones, clean boost, or balancing signal levels.
