Stick with it, the first baby steps with any instrument are just horrid!
My advice is go learn Deep Purple's 'Smoke on the Water' - it's probably one of the most famous guitar riffs of all time, but it's also one of the easiest to play!
Was introduced to tremolo'ing last night, fuck me!!, holding the pick at at angle really does make a difference!!.
I think i might just sell all my games, i now own a rocksmith console, not a 360, seems like it's all i want to play, not been that way about a game since here comes the pain on ps2, big contrast i know lol.
