Maxon CP-9Pro + Compressor

Much more than a reissue, the Maxon CP-9 Pro Plus is a completely new circuit that packs more punch and power than the original. High quality DBX compressor circuit, up to 30 dB clean boost with a compression ratio of 10:1. An internal converter boosts the incoming 9V power to 18 V, for a better sound reproduction and much lower noise. The CP-9 Pro Plus features Threshold, Ratio, and Gain controls. Reduction status LED accurately displays compression effect. Power Supply: 9 V manganese battery or special AC adaptor (DC 10 V).
CAUTION: Use only dedicated power supply when chained with other effect pedals.
