Or you could just get yourself a Monte Allums kit for the CS-3 and/or Dynacomp reissue, do some soldering and get a kickass vintage sound from a new pedal.
So far from what Ive heard and tried the best compressor out there is the Ross Compressor.Its no longer made but there are countless clones of it available. I ordered myself some parts and made my own clone. It sounds great!
