Assuming it's not a prototype, there's nothing fancy under the bonnet...
Vol, Tone & a 3-way pickup selector (Neck/Both/Bridge).
I'd venture it *might* have been re-pickuped as well as carved about - my 1981 TSB has staggered exposed poles & the p/ups aren't sealed.

Too fancy for me! Wiring doesn't look quite right, only neck pup connected to the volume which I guess might be the problem?
Mine is the same as the 400 at the very bottom of [url="http://www.matsumoku.org/models/ariaproii/bass/tsb/tsb.html"]this[/url] page - poles aren't exposed, cream pickups (which is the same as mine hiding under that black paint)
If you have any pics of your wiring, I'd be really grateful to see them so I could compare.
