So I'm about to start a new job (so funds will be available), and while I recently got a MIM P bass to compliment my J, I've already contracted GAS for a 5-string J-style fretless. This will complete my desired J-P-5 string fretless trifecta that I have envisioned! (translation: I will eventually own 20 basses). Anyway, I've read posts here regarding SX basses and their surprising quality/low price ratio. How customizable are they? Could I fit a Fender J-V neck on to an SX body? what about tuners? (for aesthics more than anything else). It would be really fun to get a $120 bass and hotrod it over time into something truly unique and my own.
