For me, it was the worst amp purchase I ever made. As good as the clean was, I could never get a good distorted tone of it. Very raspy, poor note clarity and harsh on the top end.... I played one just a couple months ago, I was reminded why I didn't like it.
I was soooo ecited to get that amp, ordered it direct and was really bummed when I got it. Vai's Blue Powder, for me, really conveys how bad the gain is on that amp.
Cleans are amazing.... No issues there.
