CHORUS SPACE-C CC300

The CHORUS SPACE-C CC300 provides four unique interstellar pathways through the sonic universe.

Analog, of Course

We took four of the recording industry’s best-sounding chorus effects and packed them into a single, convenient stomp box. The CC300 will quickly become your secret weapon of choice, thanks to the dreamy sound of its real analog stereo chorus.

Four on the Floor

The CC300 makes it so very easy to get great sound at the push of a button, or two, or three, or four. We’ve taken all the guesswork out of dialing in the ideal chorus. Typically, you would have to adjust Level, Depth and Rate controls (and hope that the stars were in proper alignment) to get these kinds of results. With the CC300, you just select one, or more, of the custom-designed presets and the chilly realm of chorus is all yours.
