Yes that's the US guitar Big Muff Pi in the video. I've always found it gets lost in the drums personally. If anyone has any tips then let me know.
As for doing weird things with amps, guitar necks, etc....I dunno though you gotta try these things yourself at least once. Even if you end up looking a little silly on Youtube in the process.
I was under the impression that tubes are fragile enough without subjecting them to medieval torture.
mind you we are talking about someone with three ampegs, one of which costs more than my car, amp and cab put together. So what the hell do I know?
Oh dear I just made myself a little sad
