Used Whirlwind OC-Bass Optical Compressor

The OC BASS Optical Compressor is both a compressor, as well as a limiter - (depending on how you have it switched). With three pre programmable attack speeds, you can switch from a super fast, thumping grab, to a long and lush compressed sustain, with plenty of adjustment in between. The OC BASS comes with adjustable input and outputs, so you can easily tailor the exact amount of punch and sustain you desire. Set the attack switch to med in the limiter mode, and turn your thumb into a registered weapon of funk. Your bass will thank you!
