So, another of my "What is this item actually called" moments.. This one has been annoying me for the last few months.
Basically, in many cheap headphones, if you open them up, inside the outer insulation layer, the two wires going to the headphone speaker will be made out of multi-stranded, lacquer/enamel/PVC/something coated wire. Turns out it's perfect for my application, since it's small enough to pack a few of them in a dremel-ed out channel in the side of a guitar neck. However, aside from ordering a whole bunch of headphones, I can't seem to find this wire anywhere! Does anyone know where I can get this sort of wire, or how to better look for it? I've searched the usual Mouser/Digikey/Google, but other than solid magnet wire, which tends to be too brittle to use, I can't find somewhere to buy this stuff.
