Sounds transparent. Will shape up the transients in an elegant way. Not a 'very caracterial' unit. Very clean signal path, no noise, hum, hiss, etc. A bit limited in what it can do, but it was expected giving the few controls... Some items on the from panel feels just a little bit flimsy/fragile (at that price, I expect the BEST and solid controls), but well made overall.
It's hard to describe the sound of a compressor with words so I encourage you to browse YouTube for demos... Some videos demonstrate accurately what this compressor is capable of.
