Boss

"Leveraging decades of research and development, BOSS’s proprietary Multi-Dimensional Processing (MDP) technology offers a fresh approach to achieving exceptional guitar tones. In real time, MDP analyzes the various elements that make up the sound, including frequency, overtones, dynamics, pickup response, and more. Various playing characteristics are analyzed as well, such as note register, single notes vs. chords, bends, vibrato amount, and others. Each individual element is then processed in unique ways to produce optimized tones as you play. With its ultra-detailed, high-tech approach, MDP delivers tone quality and playability that reaches far beyond the limits of traditional effects processing.

Powered by BOSS’s MDP technology, the CP-1X is a new type of multiband compressor for guitar that preserves the character of your instrument and technique for unlimited musical expression. Intelligent processing analyzes your signal in multiple dimensions as you play, providing advanced dynamics control that never colors or muddies your tone like typical stompbox compressors can. The simple, four-knob interface makes it easy to dial in sophisticated results, while the handy gain reduction indicator always shows you how much compression is being applied. Optimized for all types of guitars, the CP-1X offers next-generation performance for every style of music.

The CP-1X features pro-level 18-volt input circuitry that provides ample headroom for the hottest guitar pickups, ensuring exceptional clarity with any instrument. A 16-segment gain reduction indicator clearly displays the compression amount, making it easy to see what the pedal’s doing. The CP-1X’s noise performance is also extremely low in comparison with other compressors, another huge benefit brought by BOSS technology."-from the Boss website
