Sounds possible to me, most of the info says it changed about 1970 , so a transition time could probably have either, I’d have thought they overlapped at some point
I found this deep in my learning videos from a long time back when I wanted to learn more about slap , it’s not the best sound quality but there’s some good exercises on there , someone has pinned the exercises in the replies which is useful, might be worth a look
I’ve had quite a few, i like a large clear display so quite a long time back I bought one of these for not much money and its been great, a new one came up on eBay so I bought it for a spare , I was going to buy one of the expensive ones but this does the job well
Haven’t touched alcohol for nearly 10 years now ,but when I did it definitely didn’t work well with playing, I’d forget the notes ,be out of time and generally just sound dreadful.. not much different to now really 😁
Apparently there’s good and bad from all different years although I’ve never played a bad one, maybe I’ve just been lucky, yours certainly looks great, I’d be well happy with that, congrats
From what I can see it all looks good , some have the black plastic gasket under the neckplate but I’ve also seen many without it , very good condition
