To be clear, I agree with some of the posters here who feel the tone IS kind of ratty, but it's great to finally KNOW what was actually done to the amp...and I don't think anyone can argue with the tones Vai got from it (but again, I don't care for what Pete is getting from it). It would be way more interesting to sit in the room with the amp and play it, set it how YOU want it, and FEEL it before ultimately "passing judgement" on it. Don't forget, Vai never gave up the Boss SD-1 on his board even with the Jose and Lee Jackson amps, so there's that little tidbit too. I'd bet the Jose was set just dirty enough for rhythm and like so many of us, the SD-1 got the nod for solo boost chores.
