Check out the gear the guys are using on tour.
Joe Perry's Dan Armstrong
Perry is also known to play a Lucite Dan Armstrong guitar. The one he takes on the road isn't one of his originals (those stay at home). This particular one has a custom-made pickup and is tuned to open A, "Keith Richards-style", utilizing just the five top strings, but Perry adds a bass string at the low A. He uses it for "Draw the Line".
