Buddy of mine named Ron Bankley did some slide on a CD cut. I'd not seen him play it, but the sound/technique was vintage Bankley. Anyway, I asked where he'd got the instrument, he said, "Found it in a music shop. The guy wanted to get rid of it." A few other people months later asked how he'd got that great sound. Bankley replied, "Well, first you gotta get a ten dollar guitar!"
