MXR M87 Bass Compressor Pedal
The MXR M87 lets you have complete command on the compression function thanks to the release, attack, ratio, output, and input controls. The built-in Constant Headroom Technology (CHT) provides plenty of headroom, letting your compress the sound without compromising its clean tone. For hassle-free setting up, the MXR has 10-LED gain-reduction meter as a guide. Plus, M87 uses True Hardwire Bypass to keep the low end tight and clean. IT works well without impacting your tone negatively.
