    Hi guys - I recently dug my old MIM P bass out of my mom's attic where it's been for the last 20 years (I started out as a bassist in the early 90s, been playing guitar since) and I want to fix it up and start playing again. I am having a hard time finding the right parts for it though. For instance, everywhere I look, the factory P bass pots are 250k. But mine has 500k pots for some reason. Do I want to switch them out?

    What I need are:
    - Bridge height adjustment screws, or set screws (which size is correct for this model?)
    - Tuning machine bushings (I'm missing 2 of them - no clue how or when that happened. What is the right size? Most that I see say from 2001-present)
    - Wiring kit (both pots are bad - I'm looking at this setup Traditional Vintage for Precision Bass® )

    What do you guys think? Any help would be appreciated...

    An old Mexican Fender would be a good modding and upgrading platform. I wouldn't worry too much about keeping original parts.

    250k pots are more often seen in P basses. It could be that Fender simply had a line on cheap 500k pots when they kicked off the MIM production, or they wanted to make the basses sound brighter.

    Is it one of the Mexican P-Basses with the Stratocaster knobs on it? If so, I'd gut the electronics and start over. 250k pots are the way to go. I don't think the tuners they use now are any different. You could always upgrade to the Hipshot replacements that fit.

    You mean the traditional white plastic "Volume" and "Tone" knobs labeled 0-10? Yes it does. I was wanting to replace those anyway with some knurled chrome knobs. When you say gut it, do you mean the pickups as well? or just the pots, jack, and wiring?

    Do what you will with the wiring. If it needs replacing do it.

    As far as the pickups go, wire first, then listen. They might have the sound you're looking for. Then you can make an informed decision.

    Welcome on board!

    A local repair tech or music store might have some bushings.

    I suggest keep the pickup until you see how it sounds.

    Definitely replace those ugly-A-F Strat knobs. I recently saw a new fender bass that’s using those and posed the question why? Somebody’s answer was “esthetics” lol. If you like tye esthetic of a cheap POS which is how they look.

    Thanks for all the help. I believe I have found everything I needed on Ebay.

    Just the wiring. The pickup is okay. There are better ones, but there's nothing wrong with the pickup you have.

    Get 250k pots with solid shafts and some proper flat top knurled knobs.

    Tort and flats is mandatory. :roflmao:

    Post pics of the tuners on there before you jump into that lake.

    Here's a pic of the headstock in question, with the mysteriously absent tuner bushings... I've ordered the new bushings. Since I don't have a press, I'm thinking installation involves an oversized socket and a mallet?

    Socket, piece of wood, and a cheap C clamp to press it in.
