Hi everyone, I recently bought an Epiphone SG G-400 Pro with the push/pull pots, but I have a question relating to the middle pickup selector position. Basically, if I completely roll off the volume of one pickup in the middle position, there is no signal output, even if the other pickup is at full volume (or anything but off). On my old Epiphone SG (the '61 reissue model, which I no longer own) I was sure that the middle selector switch position enabled one to do a "killswitch" type effect by completely rolling off the volume of one of pickups (say the neck position) and moving from the middle position to the "off" neck position (so the middle position outputted the volume of the bridge pickup). Can someone advise whether the SG Pro should be doing this, or is it an issue with the wiring? Thanks in advance.
