    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. 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.

    Pros - Transparent. Attack & Release knobs. The LEDs!!
    Cons - Even in the slowest settings the attack is still quite fast.
    This is a very usefull pedal, which can do from light compression to strong limiting. With all those knobs, it can look intimidating for those new to the compression world, but a quick look at the manual and at the ever usefull www.ovnilab.com should put you on the right track in few minutes.

    The adjustability of the attack & release time are extremely usefull to retain (or get rid of, if that's what you are for) the initial spike of each note. One important thing to note is that, even in the slowest settings, the attack is still quite (very) fast. This is not a problem for me, but it may be for others.

    Even if the compression ratio is not infinitely adjustable, the four offered ratios have been thoughtfully chosen and so far I have not missed further adjustavility.

    Last but not least, I really hope that whoever thought about including that gain-reduction status LED meter got a considerable rise on his/her payroll. It's pure genious! For an effect so difficult to adjust just by ear as compression, that extra visual confirmation of what's going on really eases things. Well done!​

    Pros - Perfect for bass players
    Cons - premature death on mine
    I use to leave this in my effects loop with an Aguilar AG500 and a passive J. It was nice to smoosh the hard hits and deep digs, but became erratic and stopped functioning reliably. Now it works when it wants to and other times seems to just stay in bypass, although the meters still say its compressing. Was totally happy when it was new.

    Pros - The meter!
    Cons - Can be sensitive to input levels
    Many reviews out there for this pedal, I'll summarize my opinion - top notch pedal, the meter is great for setting levels, make sure you set the input levels first, very clean compression. The last part is perfect for most, but I kinda like some tone in my compression.
