Not sure if this forum has enough gearheads to know the answer or not. I'm putting together a partscaster Jazz Bass for a buddy and am wondering if the routing and mounting holes are the same for the vintage stack knob versions as they are for the later 3-knob. I already have a plate and plenty of pots for the later versions, but if the stack knob plate is a direct replacement I may try grabbing one of those and wiring that up first since he's played an original and liked that set-up a bit more. If the plate isn't a drop in for the standard version (which this body has already had installed in the past) its not worth the cost of the stacked pots and knobs to give it a try. Thanks.
