I’m curious if the community has some insight into the type of device used by Oscillatorial Binnage on their junk wok instruments. From what I can gather, there are two coils placed opposite one another along the rim of the wok, creating what I assume is a feedback/exciter device similar to an EBow.
They get some fantastic drones out of these things. I’ve done a bit of research into the EBow, and the circuit looks pretty simple: coil 1 > amp > coil 2 > coil 1…ad infinitum. There must also be a pick-up of some kind used.
Anyway, love to hear any ideas you all might have. I got junk I need to vibrate! Oh wait, that came out wrong….
