Hey Bob, mine I’ve guessed from other photos to be c1968 so that could be right. Mine has a 5 screw neck plate with the word JAPAN inscribed (no “made in”). I got it free and it had its OHSC - complete with slogans written on it and a busted lock.
Mine has a barely legible “Challenge” in script on the headstock and is 33.25” in scale (Rick scale), and 2 single coils in (comparing to photos) approximately Rick 4001 spots.
I just got it back from a couple of days at the Drs. Had Chromes put on and some surgery to reduce the action. It was high enough to limbo under before! I through the foam mute I was using with the other strings and played around with the pickup blend and hey no I get something other than thump thump thump, which I liked ok, but this is better. Maybe helped by being able to venture north of fret 7 now.
I can get a burpity bop out of it now and it is really in its own spot now apart from the Birds and the P copy. For now at least.
Do you know anything of the origin of your old bass?
No, not at all, mine was used when I bought it but I do think it was also Japanese, it had to have been at least several years old, most of the cheaper basses and guitars were made in Japan back then and sold here under a variety of names. It's an interesting topic though. It had high action but wasn't that bad, I knew nothing of set up, not even truss rods. It sounded pretty good though and was playable, I will say though that when I bought my first new P bass in 1970 that came with flats, covers, mute etc I had to raise the action because I was so used to the other one
@JIO knows a lot more about this than I do.
