1.) Are the three lugs on the right side of the CV Duo switch basicly the same as the three in the old schematic? In other words, will the three lugs on the left side of the CV Duo switch be left open?
2.) The old schematic shows the top lug of the switch going to ground on the shielding plate? Since I do have a shielding plate wouldn't the switch is already grounded just by being screwed on the plate?
One last question. It appears that the bridge was grounded to the shielding plate by a short piece of guitar string. I can see the imprint in the body. Is that how it was done on these old Duo Sonics?
Thanks in advance for your help.
