Double Bass NS design CR-M switch only works in one position.

I am getting an issue where, if I put the blend to just the piezo and the switch up on my NS design CR-M, then I get no sound.

It looks like the bass is an old model as they don't seem to sell them with switches any more?

Is there a way to fix this? Currently, the experienced Luthier who I bought the bass off (second hand) is struggling to find answers.

Thanks!

I think these are all surface mount switches and potentiometers making repair more difficult. I would try to thoroughly spray the switch with Deoxit and wiggle it a lot and see if that helps. If not I’ve called NS before, they could sell you a whole board to replace. The pickups are not soldered to the board (at least they aren’t on my newer CR5m) so it should be user serviceable if you’re patient and make sure you connect all the wires to the correct pin out on the board.

Oh... I should have said, the switch is fine apparently. It is more likely something to do with the piezo (the magnetic pickup is fine also).
