I am a closet guitarist! After a few years playing at guitar, I realized I was never going to be very good, but it was pretty helpful in learning what they can do. It's easier on kb. The newer arrangers do a lot of stuff for you that it make it sound realistic. Sometimes too much. First instrument was trumpet, then bass, then organ, all useful experience. Trumpet was by far my best instrument until basketball removed a few teeth. Started trying to sing when the singer didn't show up one night and I wanted to still get paid.
Best thing about playing a real guitar was that it made it really easy to get girls. There are several really great guitarists around here, than when one walks in I start playing piano stuff and tell them to go get their axe out of the car. Sometimes they do and I get to learn some more of their stuff!
