I just posted a review here:
http://www.ovnilab.com/reviews/cmclassic.shtml 
The short version is that this is the best
inexpensive compressor I've tried, in terms of practical functionality, low noise, and handling of the low end. This one is in very good condition, with the only "issue" being some cosmetic wear in the finish, around the sides, as the previous owner used tape to attach it to his pedalboard for god knows what reason. They sell for about $122 new, so how about I ask $85 shipped for this one.
The only trades I'm interested in at this time are compressors that I haven't reviewed yet, or the Barber Tone Press (which I
did review but I need to update that review), or certain uncommon overdrives, or high-quality cables e.g. Belden, Canare, Mogami, but no Monster.
