pickup selector switch
If you want to switch, then switch.
All electric guitars have this switch but it varies from guitar to guitar. it is called the pickup selector switch. It is used for deciding on which pickup to use on the guitar. On a les paul style guitar it can be used to select the neck (traditionally rythm pickup), bridge (traditionally used for lead) and both pickups together. =================== That's what it is on a normal Gibson Les Paul. But on a Gibson Les Paul BFG, that is a "kill" switch that turns the guitar off completely. On many Gretsches, the toggle switch is a tone switch flipping between bassier and more trebly sounds. On most Fenders, that switch is down on the lower bout by the volume/tone controls (but on a Telecaster Deluxe, the switch is where it'd be on a Les Paul). Then there are oddities like the Italia Rimini, which has no pickup selector switch -- just individual volume controls for the two pickups. Every guitar has a different design. You'd have to look into every model.
