PUP wiring

[coolhandjjl]

I took the humbucker out of my '09 4003 and returned the hi-gain to it in the RWRP mode. I'll leave this baby stock.

I have a 4003s I want to put my two Ric Humbuckers in. I ordered my 500k audio taper tone pots and 500k linear taper volume pots from tubesandmore.com, and picked up some .033 orange drop caps. The humbucker leads looks like they should go direct to the pots with no shield lug to thew bridge surround like the original hi-gain does. Do I need to add a ground wire from the bridge surround to the pot base? What about the ground wire under the tailpiece? Do I still need to connect that to the pot base?

Yes, you still need all your grounds.

Okay, thanks. The one in question is then the ground for the bridge pup. Do I need to cut into the humbucker's insulated lead (right after it passes through the hole under the plastic pup mounting plate) to access that pups shielding wire so I can solder a ground lug to it (that lug connects to the bridge surround)?

John, this may help: http://www.rickenbacker.com/pdfs/19521-HB1%20Wiring.pdf

Thanks John. My humbucker has its shield soldered right to its case, so based on the diagram, I'll run a lead from the small screw that holds the pup onto the plate, to the large screw that holds the plate to pup surround.

What does that wiring diagram mean in layman's terms? It looks to me like the two outside poles are wired in series and the north inside pole goes to ground. What does that do for the sound? I really need to learn how humbuckers work...

I read about some people who split up the leads to do more possibilities. For me, I'll stick with standard wiring for now.

The easy way to do that is to join where the two coils of the HBs are joined (It has some heatshrink on it) and jumper it to the unused leg of the tone pot (for that pickup) WHen you turn the tone all the way up you will get a singlecoil like sound with the gain structure of a Toaster and the tone of an old Hi-gain.
Peavey T-40 basses were wired this way and it worked a treat...

So it looks like all four leads run the entire length of the cord, and only at the very end, they are joined? In that short piece of shrink tube on the very end, and just two leads emerge.

WHen you turn the tone all the way up you will get a singlecoil like sound with the gain structure of a Toaster and the tone of an old Hi-gain.

I use a conventional tone pot as hi-treble to no-treble control, and I typically leave it in the hi-treble position. So which position turns the humbucker into the single coil sound?
