Pinch harmonics. My lead guitarist couldn't figure them out. A fourteen year kid showed me how to do them, and I caught on right away.

Playing Muse's Plug in Baby behind my head

I used to do that!!!! Then sort of stopped cause I realised it was a bit over the top lol.

Anyway, I dunno how hard most people find it, but I got 2-hand tapping in about 10 mins. I mean like the start of the crazy train solo two hand tapping.
