Okay, first off, get all the jerking off jokes done right now.
Second. For as long as I can remember the idea of soloing never really appealed to me. I really have no interest in learning how to solo, but what I have always be really intrigued by, was the dude making the fucking brickwall of sound behind the solo. I have always been interested in rhthym and when I start a band, I will be the rhythym guitarist. However, in order to be a great metal rhythym player (James Hetfield) you need a machine gun for a right hand. Any suggestions of how to build up speed and strength in my forearm and picking hand.
