Re: Intense guitar wiring, separate tone knobs?
After thinking about it, Artie's statement is correct about your drawing, and to a lesser extent correct about my drawing - with mine each tone control is switched in and out of the circuit with the pickup it's attached to, so when more than one pickup is on, the lowest set tone control will affect all pickups, like the middle position of a Les Paul.
Say you have all 3 pickups switched on with the neck tone wide open, middle tone at 50% and bridge tone all the way down. The bridge tone will be the load that the whole instrument 'sees'. Then if you switch the bridge pickup out of the circuit, both neck and middle will see the middle tone control at 50%. Then with the middle pickup out of the circuit, the neck tone will only see its own load and the tone will be wide open.
Hope that makes sense. There may be a way around it - I seem to recall the '62 Jazz Bass style wiring having independent tone controls and no pickup switching whatsoever - the tone controls on that have a jumper across the two left terminals of the tone pot, so that might make a difference. See if someone else chimes in...
