I have a tooth lock washer that goes with the pickup selector on a Series bass. Does anyone know if it goes on the top or underside of the brass plate? Thanks.
I put it under the nut on top, seems to work well.
Dad's preferred arrangement: switch ---> toothed lockwasher ---> [mount on plate or wood] ---> dress washer ---> hex nut
Great, thank you, I will revise the set up :)
