Good choice but I'd still try before buying.
It's a good but not very subtle compressor and for the same money (if you can solder) you can have a Monte Allum modded Boss CS3 which is similar but cleaner.
On the other hand you've got the smx fans, which is both good, subtle (IMPO too subtle but I'm a comp junkee) and controllable (and built like no other fx pedal out there).
Then there's the valve comp fans. Noisey but a sound to die for.
Compression is like boobies...any is better than none, but we've all got our favourite flavours!
