EMG 3-Position Switch sélecteur de micro style ST
With some guitars you may have to do a bit of rerouting within the control cavity because the cables that route to the humbuckers are on plastic blocks that are about an inch long and stick straight out which means they can take up a bit too much space within the control cavity.
Once installed though the switch goes between bridge/bridge&neck/neck settings and best of all it switches smoothly and there's no noise, clicks or pops as you switch between settings.
