Thanks Brendan, I have checked the switch with my multimeter and it would appear to be faulty, I have checked with guitar parts suppliers who have come up with LP or Gibson three way switches which bear no resemblance to the one supplied, (in fact they are much larger and longer and have different contact points) and at $45 I am not prepared to take the risk without checking with you.
Maybe I can buy a replacement switch from PB or Dingobass
Regards,
Peter
