Re: Bass rewiring help request!
Itsabass is right. Though some basses tend to like 250k pots so it's up to you at the end. The last jazz bass sounded much better with 250k pots. But it's up to you. You get more brightness and output out of higher valued tone pots.
3 way toggle - honestly go import, the 3 way toggles from China the only bad ones are the box ones. I've had the same no name 3 way toggles in guitars for 15 years
A250k or A500k volumes - if you treble bleed mod your guitars just go B250k or B500k
B250k or B500k tones
the capacitor is up to you. Here's two suggestions
1 - 0.022uf (22nf) if you go with 250k pots,
2- 0.047uf (47nf) if you go with 500k pots.
You can mix and match these too. Such as 22nf capacitors and 500k pots
0.047f (47nf) is twice the amount of frequencies rolled down too, it's easier to visualize capacitors in nanofarads as the zero and decimals may throw some people off which is why in all my posts I like to put nanofarads too
Thai polyester capacitors are your best choice if you need to buy some, all the vintage stuff and "hifi" is a sales pitch or to make a build look pretty. You will see more of a difference trying lower or higher than original valued capacitors than any USSR surplus or orange drop will ever get. Plus of course you can buy a bag of both values for around the price of one CDE Orange Drop (formily vishay / sprague). Anyways I've got better things to do than "pick measure" capacitors and the snake oil around them.
If there is any pots currently in the guitar measure the neck of them. Some guitars take 15mm pots, others 18mm. The only anomaly is Gibson guitars with 20mm (rounded up) shaft height on the pots. Since it's a bass your best bet is 18mm.
and here's your wiring, if anyone can't find something they are after that is not drawn out online send me a message. This is assuming the 4 wire pickups that the NYC follow the seymour duncan color code and all. I've worked on maybe 10 basses in my life so in case there is anything I'm unaware of.
for the toggle if the neck and bridge position get mixed up switch the two wires around
