Faulty Pick Switch.

[Mickyk]

Hi all.Just been playing my Yamaha bb424x and the Pickup selector switch has started to play up.I can select the Neck pickup and both pickups on with the switch set in the middle, but when i select the Bridge pup it doesn't work  even when i wobble it around a bit.Any suggestions folks.

Open the back plate (if there is one) and spray some contact cleaner to the switch. Then B - N - B - N - B - N... until the switch works well again.
