Another suggestion for the OP if in the market for another bass………….is a NS Design Radius bass. By design, it is more ergonomic than flat-backed instruments. Need to like headless basses though.
Didn’t Fender themselves dabble with this (S1 switch) in order to allow Jazz players to run the pups in series and attempt a more Precision-like sound? Seem to recall it was in some mid 00’s instruments IIRC.
I have one as a back-up in case of problems with my wireless kit. It does not have a limiter though, so I always worry about noise spikes (feedback or dropped microphones) with IEM’s and serious ear damage as a result. The Rolls PM351 is otherwise a great piece of kit though.
The extra attachment holes are normally seen on the Gotoh version of the BBOT bridge. If it came from a Japanese Fender bass it might be possible that it came from new like that. I am not sure if Gotoh stamp their BBOT bridge.
This ^^^^^^
Fender uses Meguiars in their branded products for the same intended use.
Of course, the Fender product is way over-priced. The auto detailing world will lead you to the best prices, I’d bet.
