Well I don't think I'm alone in playing a full night of HB/SC/P90 songs all on a SC Tele! The thing is if I did think this is a Les Paul song, I better grab a Les Paul for this, I probably wouldn't play it as well as I could on a Tele. I think that's most important - to feel comfortable with the guitar above all else. With the band I'm in just now we do play quite a variety of bands, but we play them with our own energy/vibe. The feeling we have is almost, this is our set of songs and they all sound like us. In reality - not quite as they are all covers but the feeling we have is to play them with our own personality and still as a tribute to the original. So I've never swapped guitars during a set really.
