the only thing is i cant get the little black toggle switch to do anything, ive heard its a bass cut or something as its got a capacitor on it does anyone have the same guitar or some pics of the switch so i can see what im doing wrong?

and the neck is a 1965 musicmaster neck, 24 inch which i have for a project, i have a jagstang body which has been routed to hell which im going to use the duo neck for

do you guys think this body is salvageable and if so the best way to fill the routes?

and the blue mustang/duosonic is a 1966 mustang neck and mid 60s duo body, with hotrails and a 3 way mini switch, it plays soooo nice.
