I've got a nearly new MXR M87 Bass Compressor for sale. I gave it a shot for a week and I've come to the conclusion that I'm just not a compressor kind of guy. It is one week old and comes with the blank warranty card. It's in perfect condition but I did put velcro on the back. I'd be happy to remove it at the buyer's request. $150.00 shipped to your door. Thanks.
