Check out the gear the guys are using on tour.
Joe Perry's BC Rich Bich 10
Another iconic guitar for Perry, this particular version of the 10-string Bich is covered in Swarovski crystals. The guitar is tuned to Drop D, and the D, G, B, and E strings are in unison, but with different gauges for a slightly varied sound. The extra switches and electronics are bypassed, so Perry uses just the tone and volume controls.
