Boss CP-1X Compressor
Boss · pedal
The Boss CP-1X is a multi-band compressor pedal for electric guitar using advanced multi-band processing to compress bass, mid, and treble frequencies independently, avoiding the squashing or thinning artifacts common in broadband guitar compressors. Features four controls: Comp, Attack, Level, and Tone. A four-LED gain reduction meter shows compression activity. Shares the multi-band architecture of the bass-specific BC-1X, adapted to guitar frequency response. Used in studio and live settings where natural, transparent compression is preferred.
