These self contained units slide into a pre drilled hole in the front of your guitar, and are hidden by your guitars knob(s). Individual cavities are easy to route, requiring only a drill press and a 1.25" forstner bit. Connect the cavities by drilling small holes inside the cavities to allow wires to pass through. When you are done you will have a guitar with hidden control cavities and no plastic covers! To access the pots, simply remove the knob and open the pod with a phillips head screwdriver.
The complete set includes a volume pod, a tone pod, and a blend pod. Also included, enough wire and a wiring diagram to help you complete your project.
