Hi, Bassassin. Sorry, I saw your post only now.
The info I included in the "for sale" post is all info I received from the guy who traded the bass to me. Perhaps some of it is a bit inaccurate, as you pointed out.
I did, in fact, look at the back of the headstock and it has neither a serial number nor a "CIJ/MIJ" marking (which I find odd, in retrospect).
That said, the rest of the info seems correct and the bass is, in fact, in perfect working order as well as aesthetically in excellent/mint conditions.
Since you seem to know quite a bit about these instruments (more than I, obviously), what do you think of the price I'm asking. Is it fair, do you think?
Thanks for sharing your thoughts. Cheers.
