Hi guys, I'm in the process of wiring up my partscaster and I can't seem to get the middle switch position to work. I've got a Texas special in the neck and a SD Lil 59 in the bridge that I've coil split through a switch. So I've plugged her in and the neck and bridge positions are working but no noise through the middle. I've wired the switch as per instructions but am thinking that I might have missed something? (Like linking some wires or such). Cheers for your advice.
