Body: I'm one of those guys who doesn't think this matters and I'd take whatever's cheapest that day under 4 lb ... but for the sake of simplicity, swamp ash, no more than 2 pieces. Finished in butterscotch (don't have that one yet) or trans red (makes it faster).
Neck: Identical to the modern American Standard Telecaster neck (fret size and all) except with a compound radius from 9.5 to 16". 1 11/16" nut width.
Bridge plate: Modern 6-saddle
Bridge PUP: Is money no object? Then Fralin Steel Pole 43 (7.5k)
Neck PUP: Fralin Steel Pole (@ 8k)
Etc: series switch or pull pot. Strung through the body, possibly with one of Taipan tone's blocks (the 6-hole piece of metal that replaces individual ferules). Heel contour (how did I ever live without that?).
....I've got a Squier pro-tone thinline that is in 9.5 out of 10 cond. and I am seriously considering tearing it down and changing the neck and electronics. The only thing I don't like is the neck ( a little thin for me), But I figure, If I'm going to swap necks, I might as well do it all, and make it totally to my taste. I'm just having a mental problem parting out/ tearing down a perfectly good 'git that has/is becoming collectable. I love the color and binding ( Crimson red/ Ivory binding ) and the ash thinline body.....'dunno, But I'm enjoying this thread and getting hardware and p-up ideas/ combos.............
