yeah i know what you guys are talking about, a way to make it easier playing standing up is to hold the guitar on like a 50 degree angle upward from the head. I know that helps me a lot while playing standing up. i know the guys from blink 182 plays his guitar down around their knees almost. that's not to wise. They think it looks cool to play down that far but i wouldn't compromise the way i play to look cool.
