Ok, I've only ever used an alesis 3630, an ART CS2, and the Nady that is the topic of this thread. I am obviously not any sort of compressor guru. However, out of those 3, I like the Nady the best overall. You have the option of an 'auto' mode that automatically dials up good attack and release settings. Of course you can adjust these settings too. anyway, it has been really easy for me to get some good vocal and guitar sounds using this unit. For the price, I think its great.
