MXR

The power of a studio-grade compressor in a compact stompbox.

Take your favorite studio compressor to the stage with the MXR M87 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.

The totally transparent M87 Bass 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.

Features
  • CHT™ Constant Headroom Technology for clear, clean performance
  • True bypass
  • 10 gain-reduction status LEDs

An essential effect every bassist should own, done the MXR way. Order now.

    With great control comes great power...or something like that. And while I was never able to get a terrible sound out of this unit (and I was trying to, just to see), I could get some effects that were definitely on the excessive side. If you want to use compression as an "effect", you can get that.

    But that's not what I was looking for, I wanted something transparent. And if that's what you're looking for, you do need to have an understanding of the basics of compression and how attack and release times, along with the threshold and ratio controls all work together. The manual does a fair job on explaining these concepts, and there's a ton of material out there if you want to read it. Just know that if you are new to anything other than 1 or 2 knob compresors, you're going to need to spend a little time learning how to drive this box. But once you get it, it's hard to give up the additional control the MXR Bass Compressor gives you.
    During the course of an evening, I'll play with my fingers, a pick, and slap every now and then. I needed something to level things out without choking the life out of the sound. One of my bands has also moved to in-ear monitoring, so I knew I definitely needed some kind of sonic "gate keeper".

    I've been looking around for a while for a compressor pedal for bass, as carrying my full rack was a little impractical for some gigs. The EBS Compressor was close, but it didn't allow enough control for my taste. When I saw that MXR had come out with a 5 knob unit, I knew I had to try it.

    One of the biggest features I miss on most compressors is being able to adjust the ratio. For me, this is huge, and can make the difference between controlling the sound, or killing it. That, along with having access to the attack and release times allowed me to set up the sound I needed in about 5 minutes. A little more tweaking on the first gig, and it's been good to go.

    Having LEDs to show actual gain reduction is a HUGE help on setting this little animal up. Plus, who doesn't love a few more flashing lights on their pedal board, right?
    I've been buying MXR products since the late 70's, and all of those pedals are still running! When I buy a stomp box, no matter what, it's got to feel solid under my feet. The latest family of MXR Bass effects absolutely meets that requirement (I'm using their new octave divider as well). Solid connections in and out, metal knobs, and nice bright LEDs. And the bypass switch...it's my idea of what a switch should feel like. I remember reading a review of an MXR pedal in the 80's, and the reviewer commented that the feel and click of the switch was positive and satisfying..."like stepping on a cock roach!" I'm happy to report that feature is still alive and well in the current products.

    One additional feature that should be mentioned is just how quiet this compressor is. I use active basses into an X2 (pre Line 6) wireless, and then hit the compressor as the first effect on my board. I can say that I can't hear any additional noise contribution from the MXR pedal. I'm not running an insane amount of compression (maybe 5dB of gain reduction), so your mileage may vary.

    Changing the battery is a little cumbersome for those who still power their pedals that way. I've got Voodoo Labs power on all of my boards...so this is a non-issue.

    The only (and I mean only) thing I'm missing on this device is a low pass function. That is, a selectable crossover point as to what the compressor is affecting. But hey, that's another knob and another switch, and more real estate.
    I don't know of any other bass compressor out there that packs what I consider the equivalent of a 2U rack mount compressor into a pedal and maintains what I consider to be great quality. I've used a number of different rack mount compressors (dbx, Symetrix, UA). All great units with their own sonic signatures. But for bass, it's hard to beat the MXR unit.

    I had this pedal for a little over a year. Just before the warranty ended, the pedal stopped working. I sent it to Dunlop and they were very responsive, helpful, fixed the pedal and sent it back to me (explaining it had a bad board). Three months later, the same thing happened and the manufacturer warranty is over. Maybe I just had the string of bad luck, but I won't go back to this pedal again and will search for another one. When it's working, you get great control over your tone. The other draw back is that this pedal won't pick up certain passive instruments (typically cheaper Basses).

      Comments about MXR M87 Bass Compressor Bass Effects Pedal:

      likely the best in the market for a very specific function that won't alter or color your tone in a bad way. You won't be able to tell it's working until you're in a live setting so don't trip if you're at home playing at low vol it's not going to be noticeable.

      Comments about MXR M87 Bass Compressor Bass Effects Pedal:

      Started acting up, and from what a pedal tech is saying, the power supply supply rail failed on me. Seems like there are a lot of cheap components crammed into this thing. Unfortunately, the size of the pedal may be a factor in its so-so reliability.

            Comments about MXR M87 Bass Compressor Bass Effects Pedal:

            By far the best bass compressor I have ever used. Very versatile. When driven hard it also one of the best bass overdrive pedals I have used.

            This is a full featured compressor so take the time to learn how it works and read up on compressors. It is worth the effort as this sounds way better than any simple 1 or 2 knob pedals.

              Comments about MXR M87 Bass Compressor Bass Effects Pedal:

              Really nice compressor. I definitely appreciated the simplistic instructions included from Dunlop/MXR. A few minor tweaks and I was up and running. The input knob is a little too sensitive for my taste. Adjusting the Ratio knob beyond 8:1 is not necessary. When switching between active and passive basses you obviously will need to make some adjustments to the pedal. Overall very pleased.

                Comments about MXR M87 Bass Compressor Bass Effects Pedal:

                This compressor was exactly what I needed in a compact pedal for my board. It's kind of amazing actually how effective it is for how small of a unit it is. The versatility makes it great for recordings or live shows and to get any sound out of it you need. I play a BTB 6 string so I needed overall compression and it makes any run from Low B to high C smooth and consistent. I was a little hesitant because of the price, but it has more than paid off in it's worth and effectiveness.

                    This compressor is easy to setup using the supplied instruction manual. MXR has a step by step guide that explains what each knob does and how to set them. Within a few minutes, I was slapping away. The volume from finger style to slap is almost the same. The best part is, if I forget to disengage the when I go back to finger picking, it doesn't affect my signal in any way. Great compressor.

                    I plugged this into my bass rig and immediately it came alive! I am using a Ibanez BTB 676 through a GK 700RB and GK 4x10 and I needed something to even out my runs from Low B to High C.

                    From bottom to top the sound is even and crisp and clean and just great. If you are arguing with yourself because of the price like I did, once you buy it, all your doubts and arguments will quickly cease. BUY THIS PEDAL!!!
