I concur.
BTW, a compressor is one of those effects that you WANT to be as transparent as possible. You almost don't want to hear it working. It should just sound "good" when it's on.
No experience with it personally, but you can find one dude's opinions on it here: http://www.ovnilab.com/ Written by a bass player and they have different needs than guitarists, but still some interesting info there.
