Product Description for the MXR M76 Studio Compressor

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.



  • Classic studio compressor in a Phase 90-sized pedal
  • CHT Constant Headroom Technology for clear, clean performance
  • Ten Gain Reduction status LEDs
  • True bypass


The MXR Studio Compressor is powered by one 9-volt battery (remove bottom plate to install), a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU, or the DC Brick and Iso-Brick power supplies.


  • Run a cable from your instrument to the M76’s INPUT jack and run another cable from the M76’s OUTPUT jack to your amplifier.
  • Set RELEASE, ATTACK, OUTPUT, and INPUT controls to 12 o’clock and the RATIO control to 4.
  • Turn the effect on by depressing the footswitch.
  • Rotate INPUT knob clockwise to increase input gain reduction—indicated by number of illuminated GAIN REDUCTION meter LEDs—or counterclockwise to decrease it.
  • Rotate the OUTPUT knob clockwise to increase overall effect volume or counterclockwise to decrease it.
  • Rotate ATTACK knob clockwise to quicken reaction time of compressor—indicated by right-to-left speed of GAIN REDUCTION meter—or counterclockwise to slow it down.
  • Rotate RELEASE knob clockwise to quicken compression release—indicated by left-toright speed of GAIN REDUCTION meter—or counterclockwise to slow it down.
  • Use the RATIO knob to select compression ratio. The 4 setting selects a 4:1 ratio, meaning that if the input level rises 4 decibels above threshold, the output level will only rise by 1 decibel.Therefore, gain has been reduced by 3 decibels. The 8 setting selects an 8:1 compression ratio, 12 selects 12:1, and 20 selects 20:1.

Gain Reduction Meter

Short string taps are an easy way to see the meter display compressor reaction time and can be helpful in setting ATTACK and RELEASE controls.
