Sounds like buzzsaw mids to be honest. He does give the illusion that he has lots of highs, but there sure seems to be lots of mids in there. Anyways, sorry for sidetracking as I dont have the real answer to your question.
lol...i just checked mine and it matches this pic of Joe Satrianis...3 to 4 on the tone, 7 to 8 on the dist....anyway i own a jsx and I* keep my mids at about 4 and my t's and b's are about 5 or 6.....Joe's mids are mostly derived from pickup switch and wah...IMO
Thanks for the help guys. I took axeshredders advice but on my marshall I set everything up one notch above what he did. It sounds fairly close now. I should be posting some covers soon.
