Picked up a 94 fender j-bass, standard MIM, one piece pick guard. Got it cheap ($50) and it works...but it's spent time in a dungeon (i mean, basement) I"m guessing from the surface rust on the pickups, bridge, wire 'director' screw on the head. It has a rattling tuner, and the pots were a mess and the tone pot isn't coming back to life all that well. So...figure why not update/upgrade it? Should be easy enough... till I start googling things...Fender made a lot of models of bass' and I'm lost as to what the differences are. MIM, MIA, deluxe, std, vintage... Since I need tuners I started there...they seem to be the most diverse..vintage, std, squier, deluxe...what fits/works and is cheap (option A) and what is a decent upgrade? Seen prices from $20ish to over $100... I don't want to invest a ton in the axe...$200 at most. Figure I can get my money back out of it if needed. Replacing the bridge is easy..std or gotoh 201. Don't really want to change the sound or put 1/2 my budget into a badass/babicz. Wiring...seems the bid choice is large orange cap or not...what's the diff? (passive and plan to keep it that way). It has 2 'true' jazz pickups, not a humbuckers or P/J. Lots of choice on ebay for $20-35. I can solder but they sell some all set to go and mounted...knobs and all. Not sure what to avoid, or what I"m looking for (specifically) or if it even matters. Seems 99% of j-bass' have 2 piece pick guards..except mine of course. I always seem to get some red-headed stepchild thing. Will any 2-piece fit or is there some kind of 'gotcha' out there I need to watch for? If I opt for the mounted pots I'll need a new pick guard. And lastly, it's my son's axe and he's interested in a color change. I've painted cars and bikes so figure i can pull it off. What paint is normally used? I don't think I"m after a vintage nitro finish.
