Bumping this just to amuse myself, although comments by experienced luthiers and repair persons are always welcome.
Rather than use the Fernandes Nomad as a platform, I've decided to use the Samick Greg Bennett MCR-1. Same 25.5" scale, but the body is more of a P style so it will balance better on a strap. Also has an angled head, so no need for string retainer. Base cost is cheaper, by ~$200.
Still going to defret, string with Fender 9120s, replace strap buttons with Grippers, and change to black hardware. I'm going to use the Graph-Tech Ghost pickup-loaded, Hipshot A-style bridge in black, wired passively straight to jack, initially. Also, going to fill original pickup and electronics routes and refinish in metallic blue, to honor my old Ashbory.
On paper this looks to be a total cost of $700 + or -. Not bad if it works. Not a terrible waste if it doesn't
If I decide I need the Acoustiphonic preamp, I'll also add an LED light and preamp on/off switch.
