"Kimberly Kay" resting on a chair w/ some stomp pedals on the floor
A 1960s(?)-era Kimberly Apollo II guitar that Billy bought for $60 from a pawn shop in Madison, WI, this guitar was used for the howling feedback in Mayonaise, and on 1979. Billy has nicknamed it "Kimberly Kay". It made an appearance on Kerry Brown's blog in Sept. 2009, including a brief video of riffs from "Astral Planes" through a Binson Echorec, and again in June 2011, when it was used to record Oceania track "Panopticon".
