So as I understand the Vista JM's have a true 24" scale neck, unlike other versions that have a "conversion neck". My question is if one type of pickguard fits them all.... seems unlikely.
Hmm, I wanted to put a 3 switch Jag plate in the LP toggle position to use as a coil splitter for each pup and an off switch for the neck position. I dont think I can find dpdt's that fit that plate tho.
You don't need DPDT for any of the functions you just described. A simple on/off switch should do. That said, Jaguar slide switches ARE DPDT so I don't know what the problem is.
