I really enjoyed the whole thing, great collection of guitars and effects...should be able to get any sound he can think of.
One thing I was wondering about they didn't mention-is Vai still using those True Temperament fretted necks, I didn't see any on any of the guitars they showed...there were pics in some magazine of them even on his couple of favorite axes?
One other comment he missed the boat on a bit, waseven though his Jem series has been going strong for 25 years, Les Paul has him beat by a few years in the signature guitar dept.
Oh if you think she's a bad interviewer(which she isn't) go watch some other PG ones, those idiots remind me of the local Guitar Center rejects.
