MXR M87 Bass Compressor – Precision Dynamics in a Compact Pedal

Give your bass a more consistent, polished sound with the MXR M87 Bass Compressor. From gently evening out fingerstyle lines to controlling slap peaks or adding heavier compression, the M87 gives you detailed control over how your bass responds.

Dedicated Attack, Release, Ratio, Input, and Output controls let you tailor the compression to your playing. The clear 10-segment gain-reduction meter shows exactly how much compression is happening, making adjustments easy onstage or in the studio.

• Versatile compression: Dial in subtle peak control or a more pronounced squeeze.
• Adjustable attack and release: Preserve your initial punch or smooth out sharper transients.
• Constant Headroom Technology: Designed to maintain clarity and ample headroom.
• 10-segment LED meter: See the compressor respond to your playing in real time.
• True bypass: Keeps the effect out of your signal path when disengaged.
• Compact, durable enclosure: Fits easily into a working bass rig.

A practical addition for bassists who want tighter dynamics, controlled peaks, and a sound that sits confidently in the mix. No power supply.
