I have a Jazz style bass (for those of you who dont know thats two single coil pickups two volume pots and one tone). Im planning on putting 2 on/on dpdt switches in it for phase inversion. Is it possible for me to put another dpdt on/on switch in it after the volume pots so I can switch between series and parellel? Im used to no pickup selection switch so that isnt necessary.
Cutting the tone pot out should be very straightforward. But I can't understand exactly what you are suggesting. All you need to do with the switch is use it to disconnect the tone control from the circuit.
You could have two phase switches if you want. But it is a bit redundant.

Ok on a spdt switch there are 3 lugs. I'll call them the top, middle, and bottom. Now the top lug will go to the tone pot then out. The middle lug gets connected to everything before the tone pot (pickup selector volume pots and pickups in order). Then the bottom lug gets connected to the output. Would that work as a bypass?
The main signal doesn't actually pass through the tone control. The way it works is that the tone pot provides an alternative route that allows a variable amount of treble to take a shortcut to ground.
So wire it without the tone pot first. The attach a wire from the hot side of the jack to the middle lug of your SPDT. The attach the tone pot wire to one of the other lugs. That's it.
Have a look at the articles on GN1 about wiring up tone controls to get a bit of background.

I dont care about tone bypass. I just want to know how I can wire 1 DPDT switch to change between series and parellel. I couldnt make sense out of chrisk's teleblender. There was no series/parellel blender so Im still lost.
Yes, but the volumes will play up. ChrisK's series/parallel blender is one of the diagrams in the "module" thread started by Unk on the schematics subboard. Sorry, I hadn't realised it was so well hidden.
