MXR Pedal Bass Compressor M87 Guitar Effect
MXR® Bass Compressor M87 – Studio-Quality Compression for Bass
Take your favorite studio compressor to the stage with the MXR Bass Compressor. Designed specifically for bass, this pedal delivers recording-quality compression with Constant Headroom Technology™ and true bypass switching, keeping your low end tight and clean in any performance situation.
A complete array of controls—Attack, Release, Ratio, Input, and Output—makes it easy to fine-tune your sound, from subtle peak limiting to hard-squashed compression effects. Its CHT™ Constant Headroom Technology provides plenty of headroom and clear performance, while the totally transparent design allows your full dynamic range to shine through until your signal reaches the compression threshold. The threshold is indicated by ten highly visible gain-reduction status LEDs, giving you instant visual feedback on your compression level.
It's all packed into a durable, lightweight aluminum-housing pedal that's the size of a Phase 90—perfect for any pedalboard. True bypass switching preserves your tone when the pedal is disengaged.
