Hey Gregg, I too am a 60 year old guy who has played rhythm guitar for years (with some band experience). When I lost my job I decided to try and switch to lead, which I'd always envied, so I joined GT. I found it very difficult at first, because (at least to me) rhythm and lead require very different techniques. It's taken me about a year of practising 6 or 7 hours a week to be able to improvise my own blues solos. I'm really please about this 'cos it's been like a lifetime ambition. I've always envied lead guitarists!
GT helped on this a lot (they aren't paying me to say this) but like the other guys have pointed out, it ain't an instant solution. Good luck with it all. Steve
