I've played classical guitar for 50 years; started when I was 12 or so. I studied seriously for a while, and even gave lessons while still in high school, but I went to college with Eliot Fisk and Sharon Isben and they were a LOT better! So I retreated to just playing for fun. My son, though, is serious about the violin and in the last few years we've been working on violin - guitar duets: Paganini, Schubert, etc.
I wish a forum like this had existed when I was starting out ...
I'm hoping to get information on material I should be looking at and, of course, the usual round of recommendations on strings, luthiers, etc.
