The Fish Press compressor is based on the vintage "squeezer" circuit. This pedal provides studio grade compression at the click of a switch. Unlike other compressors that "step" on your signal, the Fish Press allows the user's natural tone, and harmonics to come through. With two knobs on top of the pedal, the Fish Press is extremely versatile. The Squish control allows the user to determine how much signal gets sent to the compression circuit, itself. The Volume control allows the user to boost the signal coming out of the pedal, if necessary.
