Maxon CP-9Pro+ Compressor

The CP-9 circuit provides a very smooth, transparent, almost "glassy" compression with an extremely low noise floor, even at maximum settings. Your guitar sounds like your guitar, only with a smoother, more balanced dynamic response - Notes jump off the fretboard with stunning clarity and limitless yet controlled sustain.

The CP-9's internal voltage doubler provides massive headroom with full-range frequency reproduction. It can be used with any instrument and for a variety of applications - send into an amp's front end, place in a loop, or use as an outboard processor for home recordings.

With up to +30 dB of clean Gain, the CP-9 Pro+ can also be used as a straight clean booster or as a volume attenuator to clean up an already dirty amp by reducing input level.

The CP-9 Pro+ provides studio-grade compression in a portable stompbox format - you'll wonder how you ever played without it!

An internal converter boosts the incoming 9V power to 18V, for a better sound reproduction and much lower noise.
CAUTION: use a dedicated power supply when chained with other effect pedals.
