Anyone that's tried to re-wire one of these min-Casinos will know what a nightmare it is - no back cavity and no space inside the body to work with! You have to either go in through the f-hole or the pickup hole. I have left the tone knob out for now, as while I was trying to fit the wiring loom back in the guitar I broke one of the connections going to the master varitone. I currently have it wired up with a bridge and neck volume, and a master volume. I have a Casino coupe with a p90 in the neck, and a wide-range pickup in the bridge. I have been trying to workout how to install a varitone, preferably without having to pull all my current wiring back out! Hi - I was wondering if anyone could help me.
