I just picked up what I take to be a 70s/80s Japanese Jazz. It’s badged as Yasuki which I can find almost zero information on. I dropped Bassassin a mail before I bought it just for some tips and he pointed me to SH73’s post about his unbranded Jazz. This bass has similar rounded pickups, it’s a dark natural colour and has a serial number on the neckplate. I plugged it in and other than the action being terrible and the strings very old, it’s sounded like a Jazz. It’s heavy but not outrageously so.
I noticed with the truss rod is at the base of the neck but unlike SH73’s bass I cant see it unless I take off the scratchplate, maybe not the original? I don’t know much about Jazz basses never mind old Japanese ones.
It was very cheap but is filthy and one of the scratchplate screws is completely unscrewable so I’ll have to work out how to get it out!
Any info would be much appreciated!
