Re: What type of pickup selector switch for an RG550?
if i remember right the fender 5 way switch fits one direction but not the other. There is a flatter side that has to go toward the outside of the guitar and the side with the spring goes toward the inside. It will do bridge - bridge middle- middle - middle neck- neck
there are a number of 5 way switches and most if not all should fit. if it is was an S series i'd be a little more concerned but you should have plenty of room in the 550.
Great, thanks! DO you happen to know if these RG knobs will fit on a normal pot like a CTS or Seymour Duncan? Or is there like metric size knobs? They look like normal strat knobs to me
