not really a reply to your post, but some musings on it. i must say, although my technique has got alot better over time (i can play and sing without really thinking about it for example), i'm still pretty ashamed of the standard of my guitar playing :oops:
i used to have an extremely heavy handed touch, and broke low Es and As almost every week. i changed to size 11 strings and roller/graphtech bridges which seemed to help, but on reflection its my opinion that at the same time my picking got more consistant, although its still rather hard and emotional, and probably always will be.
i've tended to concentrate on improvisation and townshend style techniques, although i'd love to improve my shredding which is pretty much entry level standard.
obviously its all about the practise, but i'd rather concentrate writing new material. someday i still hope to be a half decent player.
