I have an Ovation Breadwinner, S/N E00679, that I bought on eBay last Spring. I live about 2 hours from New Hartford, CT, but I see that Fender has closed that facility down (Fender-owned Hamer is in there now, I think), so I’m looking for a source for parts.  My Breadwinner (in textured black with the gloss neck back) seems to be complete and in VG condition, with only 2 or 3 very small dings in the upper edge of the body. Unfortunately, all the control knobs and a toggle switch are missing, and somebody has gouged all the potting out of the neck pickup, for reasons I cannot understand. I’ve downloaded every wiring diagram I can find, but can someone tell me where I might find spares and how to check if the active electronics and pickups are OK, and what sort of potting should be used once I've checked the pickup and I'm ready to put it back together?

Also, are the pickups on this Breadwinner single coil, humbucker, or what?

Thanks for your help!
