With a four-string, the middle range is less of an option. That kind of 5th that you play on those A and D strings isn't there. So a lot of traditional rock sounds, you can't play them. But to be honest, there was no particular intention when I started playing with four strings. It just worked out that way and it sounded cool.
Bill OrcuttI did pull out my old Telecaster, and have been thinking I'd like to play that loud with a drummer. But I haven't actually done that yet.
Bill OrcuttI had a guitar sitting around, and it just happened to have four strings on it, and I would sit around watching TV and playing it. I ended up writing bunches of songs around four strings.
Bill OrcuttA horn has that voice quality, and an electric guitar can emulate that. But playing an acoustic, the notes don't sustain like that.
