Re: Wiring help
i'll try and explain the "internal series" and "all parallel" thing ...
this is going to be a very simplistic explanation of the 'circuit' created by the pickups and switches, etc ... it will not be completely accurate in the details, but it will serve the purpose to illustrate the points i want to get across ...
in a traditional humbucker wiring, the two coils are wired in series internally ... which means that the electrons flow around the wire coiled around the first bobbin, then they go immediately into the second wire coiled around the second bobbin until they exit and go on their way out to the guitar to the amp ... it is the arrangement of the direction of the wind that gives the humcancelling property and this series arrangement gives it 'oomph' ...
if you have one pickup coil, and the electrons flow through it and then go to your mini toggle switch, the only place for them to go next is 'out the door' ... you can have the signals from as many coils as you want meeting up 'at the door' ... this is all parallel combining because none of the coil's outputs feed another coil's input?
in your arrangement, if you turn 'on' both of the bridge pickup's coils, you get parallel combination - not traditional 'internal series' humbucker ... there's nothing wrong with this, it is just different than what most people think of when they say they want a humbucker sound ...
if you wanted to preserve 'internal series' as an option, you could use an on-off-on mini toggle (one each per pickup) ... in the center (off) position, the pickup would be traditional humbucking ... each of the end (on) positions would correspond to splitting that pickup's coils (one for screw / one for stud) ... then you'd need a way to select which pickups were on ...
i suppose you could wire the output of each on-off-on to it''s own 'on-off' ... this would determine which pickups signals get routed to the output, but would not be simple to use on the fly for live work ...
this helping?
