CP-47 Pressure Tank

The Caline CP-47 Pressure Tank is an optical compressor based on the Diamond Compressor circuit, offering natural compression characteristics in a compact, affordable format. It works well with both guitar and bass.

The three-knob layout covers Level, EQ, and Comp, with an internal Hard/Soft switch for different noise reduction characteristics. The optical compression circuit provides smooth, musical dynamics control that maintains note clarity and sustain without obvious pumping artifacts.

For bass players especially, the Pressure Tank excels at adding definition and punch while taming dynamics. True bypass switching and a full metal enclosure complete a package that delivers serious compression capability at an entry-level price point.
