Great find for a tenner!
Well worth doing up a bit, they're actually very nice basses, especially the necks.
I've got an STB J and P, paid £40 each. The P I gigged solidly for the best part of a year I liked it that much. I did put a Quarter Pound pickup in it but the original was fine really.
The J has a pair of the Entwistle PBXNs wired with a series switch. Proper J tones with either pickup and a lovely full fat tone when in series, almost P sounding. In fact I used it for rehearsal last week, it holds it's own against some expensive 'real' basses.
Both have had black pickguards and bridge covers added.
Arty farty (bad grainy) shot 🙈
Forgot to say that the Jazz was sent to me by courier in a single black bin liner taped shut around the neck with the headstock sticking out. Amazingly No damage, crazy!.
