Excellent review just posted by Si:
Conclusion - which makes a very fitting summary to this thread:
"This is one of, if not the best pedal format compressor I have ever used. Being a VCA circuit it's not a one trick pony, lends itself particularly well to transparent compression anyway, but coupled with the advanced features here its capable of incredibly transparent levelling to help 'glue' your bass into the mix better. Or fast enough attack speeds and extreme enough ratios and thresholds to make compression a fun in your face effect or super fat core tones completely achievable.
If you want a tool to help on the gig, or to get a 'signature' compressed tone or a device in your hands to help you really get an understanding of what compression can do for you then this has to be really high up on your list. It certainly deserves to be there."
