The obvious answer is that one is a backup in case of a broken string, but Ed always switches between two throughout any given gig. Anyone know if he keeps one in a different tuning, or another reason he switches between two?
Yes, that's a possibility, maybe he chooses a particular guitar for a particular track based on the sound of that guitar. He's always had one guitar with a whammy bar and one without, maybe he chooses which guitar to use based on that. Thanks for the reply!
