I have a problem with speed... it seems as though there is a problem with my picking/fretting hand coordination and it severely limits my speed to about 128bpm at 8th notes (about the speed of the intro to "Sweet Child o Mine" by guns n roses) and it seems as though no amount of practice will improve that... I was trying to play a song called "Future World" by Helloween and the speed limit made it impossible for me to play that song, at least the intro riff.
I just started this site I decided that I am starting from the beginner lesson, now just getting the major scale down... I play bass now but its no reason to stop playing the guitar... im sure most great guitarist are good at both...
