Re: Billy Gibbons & Joe Walsh - slide tunings?
I've seen a YouTube video of Walsh playing RMW back in the old days, where he switched guitars between an extended talkbox solo, and the slide solo that followed. Makes me think he maybe used a different tuning, but who knows?
Either way, that rates up there as one of the all-time great little bits of rock and roll music, that transition from the talkbox solo, "Wout-wout-wout-wouuuww, wout-wout-wout-wouuuww", and then, short crescendo, BAM!, band entrance, slide solo, outro, the works. Fun stuff.
