Isn't it weird how most guitars don't have anything telling you what the switch does because everybody knows what the switch does. Yet the Les Paul, a guitar built for a really smart guy, had to have and still has to this day a little semi-permanent plastic piece telling you which way is Rhythm and which way is Treble. As if anybody ever really used those terms to begin with. Guitar players are weird.
What pups are in ya Gibsons? Mine came used with antiquity neck and antiquity JB at bridge... !! Its a good old school trash metal to sweet thick G&R tones at neck..
