TBX component values for bass?

    A few questions, compiled:

    1. I see a bunch of TBX kits on Ebay, but they're all "Strat/Tele" labelled. Is that due to component values differing from a bass version?

    2. What component values do the old Jazz Bass Specials (or any other 80s Fender with a TBX) use?

    3. Modifications to the stock design that anyone has found preferable?

    The schematics for my 85 Fender Jazz Bass Special says the TBX had a .022 cap. The 2 volume pots were 500k.

    I later changed the pickups to Seymour Duncan, but kept other values the same.

    I have used the same set up in a Warmoth JJ and PJ with good results.

    I'm trying to restore a 1985-86 MIJ "PJ Bass". Could an original owner of a "PJ Bass" verify the values are the same as these for the "Jazz Bass Special" ?
