Why should a guitar be anything but a couple of pickups and some resonating metal, if it is to be used in this form of abstract improvisation? These questions began to form in my mind a “guitar” whose only purpose was to suspend metal “string objects” and amplify them.
Combined, the plank guitar and ferrite bar reminded me of an instrument I played many years ago. The sculptor Andrew Gangoiti also built electric guitars. Once, as an exercise in speed and simplicity, he made a four-string guitar from a plank, no real way of tuning the strings, pickups made from some found magnets wound with however much copper wire he had lying around, connected to a 0.5 watt speaker built into the hollowed-out end of the plank, powered by a 9 volt battery. The moment you turned it on it started to feed back. Pressing your finger against the circuit board for the speaker would short out connections and alter the pitch and tone of the feedback. It was impossible. It was magnificent.
