Dunlop MXR M76 Studio Compressor Guitar Effects Pedal. The Studio Compressor provides recording-quality compression with Constant Headroom Technology and true bypass switching for clear, clean performance.

The MXR design team took a classic recording studio fixture and stuffed it into a pedalboard-friendly box. The Studio Compressor features Attack, Release, Ratio, Input, and Output controls so you can fine-tune your compression level-from subtle to squashing-right on stage with visual feedback from a bright LED gain-reduction status meter. Constant Headroom Technology provides tons of headroom for clear, transparent performance that's as dynamic as you need it to be. It's all packed into a durable, lightweight aluminum-housing that's the size of a Phase 90.
