I’ve had my ‘72 jazz since ‘82 and played it continuously since in some very smokey stinky dives. The natural finish and maple neck have consequently aged well. Other bits have not, and the original pickups went in the bin years ago. The wiring and pots followed not long after, before vintage collectable was ever a thing. Aftermarket pickguard replaced the cracked original, and hides very rough routing where some monkey tried installing a P pickup, before I bought it. Not sure where I threw that. Probably the same place the original plastic nut went. However I do still have the original tuners and bridge saddles in a box, replaced by ones that actually work. As do the Fender vintage 70’s pickups installed a few years ago. Plays and sounds nice but realistically it’s a Frankenstein.
