Here is a very sweet old MIJ bass in ridiculously good shape for it's age.

The wiring LOOKS original. See photo.
But...the battery compartment does not have a battery. 
It is NOT active electronics.
Precision and Jazz pickups.
The pickups have polepieces that look different from each other and I don't know if they came this way. Any mods were done far prior to me getting this instrument.

The bass guitar plays excellent and sounds HUGE. It's a remarkably comfortable bass for under $1000.
Massive and varied tones.
Smooth narrow neck, like a Fender Jazz. Slinky!
And around FORTY YEARS OLD vintage, it still looks SHOWROOM!

Sold as is. Ships in a gigbag.
Ask questions.
I will help.
Thank you
