I installed the retro caps and resistors as per the original wiring

I played the bass in this format for a week or so. You know how Jaco Pastorius always said he replaced his original stack knob layout with a three knib layout because the original "lacked punch"?
Well, I now know what he meant. The original wiring with the linked resistors gives a lovely round tone, but the output is noticeably lower than on a "modern" wiring layout. Also, the original style wiring means that turning down the volume on either pickup retains the round bassy sound - you can't get the classic Jazz Bass "honk".
So, I rewired the controls.Ii kept thepaper in oil caps, but used the wiring format used on the current Fender USA Reissue '62 Jazz Bass. I now have full pickup "throaty" output, and can get the "honk" when slightly rolling back the volume on either pickup. I'm a happy boy.
