Love the meter!

I've used a few bass compressors. Most fall into two categories. Either I can't tell they are engaged (transparent) or they color the tone more than I'd like. Much of these two things are cause by one thing...my poor skill in using a compressor. It's a wonderful tool when used properly, but a total tone suck when used improperly. The MXR Bass Compressor has done something no other compressor has done. It's taught me how compression works through the use of the meter on top. Now, to all you pro players who are laughing at me now...go ahead....but we all have to learn somewhere. With only a few minutes of twisting the knobs, watching the meter, and listening...I was able to dial in exactly what I wanted. I was able to fatten the tone, take the spikes out, and provide the FOH guy a good, level, signal.

Awesomely Good

By far the best compression pedal I've owned. Like night and day between this and the Ashdown model I was using. Plenty of control for any type of playing style or passive/active basses. Brings out the high notes when slapping it and adds plenty of sustain when you want it. Clear meter in compact rugged case. Also love the Blue 'on' LED. Well worth the money. Can't go wrong with pedal!!!! Can't recommend it enough. Stop debating and purchase it !!!!!!

One of the best bass pedals to own

What's there to say - this thing has the reputation it does for a reason. You won't be disappointed. Arrived in great packaging in a very timely fashion. Nothing but thumbs up across the board.

I use a few elaborate rackmount compressors in my studio to record my bass and searched for a way to bring that same great sound to the stage. When I found the MXR M87 Bass Compressor, my search ended. You get all the control and quality of a rackmount unit in compact pedal form!
