I've been watching a lot of Paul Gilbert videos here lately, and something that's been ripping at me for a while now is rather or not he's resting any part of his arm or hand on the guitar. From certain angles it looks like he is, but from others...it just looks like there's no contact being made at all. Same with Brian Carroll (Buckethead, whatever.)

Anyone know? Probably seems pretty stupid...it's just been gnawing at me.

Most if not all decent guitarists rest their palm on the strings. It's incredibly hard to mute unwanted noises otherwise.
