Haven't done the "from scratch" yet but that is my goal eventually. Currently I build my custom "hot rods"--mostly Fenderesques...I have a Strat, Tele, and Jazz Bass. I had a Charvel Star but sold it.
Strat: Stew mac 3 sunburst trem body, All parts 70's maple/rosewood neck, white Duncan Classic stacks, sperzel locking tuners, gold hardware, black pickguard, white knobs. Looks like SRV with a 70's headstock. Has on off for bridge to get a neck/bridge tele sound.
Jazz: All parts(?) Alder body tung oiled, Mighty Mite maple/maple neck, EMG J/J set with Vol/pan/tone on jazz control plate, chrome hardware.
Tele (IN PROGRESS): Stew mac 3 sunburst body, Mighty Mite birdseye maple neck, chrome hardware, diamond plate pickguard, Duncan JB, chrome flame humbucker bridge. Still need to get Sperzels and Tele neck (Duncan probably) pickup. Maybe later GraphTech piezo saddle pickup system.
