I spent over an hour at Guitar Showcase in San Jose (great independent store) A/Bing the M87 with my EBS Multicomp (latest generation True Bypass) in my "drive" pedalboard setup.
The MXR is WAY better for limiting transient peaks for slap bass style, than the EBS. I also found that the EBS added an unpleasant midrange bump (in multiband mode) that was the exact opposite tone you want to boost when playing slap bass. I think the EBS is GREAT for fingerstyle and tapping, but fails miserable with slap bass. The attack comes through and is not adjustable, and it's the attacks that need taming. The M87 was WAY more transparent sounding, and I could dial it in so it only came on with hard hitting slapped low notes. The metering is the icing on the cake.
Long story short, I sold my EBS and am getting the M87. It is not the quietest pedal out there, but in a live rig, it shouldn't be noticeable. I imagine for certain settings the noise will be more noticeable, but for my purposes (peak limiting for slap bass), it was just as quiet and perhaps quieter than the EBS. I HATE those internal trimpots on the EBS--like duh, put it on the top of the box!
Buy the M87, for the price, you won't be disappointed!
