at the end of the (incredible) X-ray eyes solo there is some very subtle almost fixed wah wah tone.Is that right?I hear that on Michael lee firkins first album as well(on a couple of solos)

Just another example of the brilliant guitar work of guys like these,and Im sure it was the first time someone had done this(use the wah for the most subtle variations in tone possible)

You are correct, man. Thank you.
