David Dyke, craft supplies and www.axesrus.com which can be cheap.
Huh, potentially some good deals on bodies there. But, bizarrely IMO, very few necks listed with more than 22 frets ....
(I keep thinking the way to my dream of a PRS-inspired best-of-LP/Strat-combo is making my own guitar with a 24-fret, 25" scale maple (or similar) neck to a mahogany (or similar) body (maybe with, maybe without a maple top, I dunno) with decent upper fret access. That seems like such an
obvious way to make a good, versatile guitar that I can't believe the market is not awash with them. But, no, it's all LP and Strat (and, these days, Ibanez) copies .... :P
