The Boss CP-1X Compressor for guitars is a new type of multiband compressor with impressive, intelligent operation. The CP-1X preserves the natural character of the instrument as well as the expression and dynamics of the individual playing style. With many compressors, the sound becomes flat or undynamic and dull - the Boss CP-1X Multiband Compressor is the exception. The internal processor analyses the incoming guitar signal on several levels for advanced dynamic control ( MDP technology - Multi Dimensional Processing). Control is intuitive via the 4 knobs on the user interface, which also features a Gain - Reduction display. The strengths of the Boss Compressor lie in the natural compression and the great clarity of the sound. The digital circuitry also reduces noise, which is a well-known problem with compression. Even with 7- and 8-strings, the intelligent dynamic control delivers excellent results in the upper frequency range while preserving the bass content. Electro-acoustic guitars can easily switch from soft fingerpicking to strong strumming without losing harmonics.
