i cant find the wiring diagram for a yamaha rgx a2, just wondering if anyone has installed a tone knob and how they went about doing it!!?
a tone knob isnt very tough to install..

head over to the 'ultimate wiring diagram thread', and take a look at some of the diagrams.. you should be able to figure it out from there.. if not, ask in there. thats the place for questions like this
thank u, i just asked just waiting on reply. yeah but it has an LED attatched to the 2 knobs on there, so there isnt much room for anything
