This bass guitar is handed painted by me. I was given this instrument, of unknown brand (the name appears to have been sanded off the headstock) several years ago. It was black at the time, I sanded, repainted and lacquered the front. I used to tour with a band in Surrey until 2019 and this bass is therefore well-used. Part of the nut broke off around the time I stopped playing so I haven't played it in many years.
If the nut were to be replaced and it set up correctly it should be playable again, currently there is a lot of fret buzz. The electrics/pickups always worked fine.
