## Overview

The MXR M87 Bass Compressor is a professional-grade analog compressor pedal featuring CHT Constant Headroom Technology for transparent, dynamic bass compression. It offers precise control with Attack, Release, Ratio, Input, and Output knobs, plus ten gain-reduction LEDs for real-time visual feedback. Housed in a compact, durable aluminum chassis with true bypass switching, it’s designed for both stage and studio use, powered by a 9V battery or adapter.

## Description

Take your favorite studio compressor to the stage with the MXR Bass Compressor. 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 gives you plenty of headroom and clear performance. This totally transparent compressor allows your full dynamic range to shine through until your signal reaches the compression threshold, which is indicated by the ten, highly visible gain-reduction status LEDs. It's all packed into a durable, lightweight aluminum-housing pedal that's the size of a Phase 90.

Review: Great device. - The M87 has a quite a few features that the others do not have. The first noticeable difference is the LED meter. While this is almost common nowadays on rack mounted compressors, it is not on pedals. I found the meter to be quite helpful in adjusting the input and output controls, along with the release, attack, and ratio adjustments needed to get the performance out of the pedal that I wanted. Another great feature of the M87 is the input and output ratio. I was able to adjust my input at a higher level, and keep the output at a lower level to give a more balanced and level sound for the different styles and techniques used. The M87 also has a foot switch that allows you to have the pedal on, or in true bypass mode with a blue light as an indicator to let you know which mode is currently functioning. The M87 can be powered with one 9 volt battery or with an adapter/power supply. The housing is small and durable. Everything is detailed to read in an easy way and this device is a powerhouse that everyone should have in their lineup. The instructions that came with the M87 are very thorough, which makes it easier for those that may not yet fully understand the aspects and effect that a compressor can have on your sound.

### ⭐⭐⭐⭐⭐ Happy with my m87
*by J***G on October 9, 2012*

Bass compression is a subtle tool/effect that is easily misunderstood, misused, and underrated. After lots of time debating the hundreds of compressors out there, I decided on this one for 4 things: 1) Functionality - the kind of controls that you get here aren't usually found at this price. The LED metering is great and lets you know how much input to dial in, I only know of a couple other that do this, and they go for $250+. 2) Ease of use - the manual gets you up and running in minutes, but patience and more use will allow me to fully utilize this effect 3) Sound - fattens my tone like a compressor should, but will also work as a limiter when the situation calls for it. 4) Reliability in the manufacturer - I've heard about a number of these not turning on, not responding to inputs, hissing, etc. For my money, I wanted peace of mind in a trusted brand like MXR. P.S. While the manual won't tell you, this pedal will also accept higher voltages, and I run mine through my 18V voodoo. I'l put a picture up soon.
