I was harvesting, and came across something.. There are quite a few of them on the neck-board, on the pcb they are labeled Ennnn, they are small beige 2-lead plastic packages that have a very small slit in the middle that penetrates about 1/2 way to the bottom of the package, and a green line on one side of the slit.. They seem to have infinite resistance in both directions, don't seem to be set up in L/C configurations, if not for the >20M resistance I'd think they were some kind of jumpers..
