I never changed them until they broke. I’ve worked with a lot of great guitarists in the studio, and some of them—like Robben Ford—would change strings after every solo. That drove me nuts at the time. But maybe it wasn’t so bad, because I guess they could hear them going dead. My ears didn’t hear it—and I don’t know if the microphones heard it— but they heard it, so whatever made them happy. I don’t think Robben Ford still does that, but he still plays his kazoo off.
