I've recently begun playing with a rock cover band after a 20 year absence from active playing. In addition to standard (E-A-D-G) tuning, we've been doing songs that require dropping all strings down a half step, as well as drop D tuning. Should we start gigging, I figure that I'll need to buy a second bass, or switch to a 5 string. I'm curious to know how other bass players handle this.
