P-90 Stack Wiring Question

Post by ozziebluesman » Sun Jul 05, 2009 4:31 pm

I am trying to wire up a Twin Neck Lap Steel that is on the workbench at the moment. The new owner only wants a volume control for each pickup.
The pickups are a set of the new Seymour Duncan P-90, noisless stacks and I have a pickup positioned in front of both bridges. As per the wiring diagram that come with the pickup I have red & black to hot and green, white and bare soldered to ground on the top of the voulme pot.

So how do I wire up two volume pots to one output jack?

Cheers

Alan

seymour duncan has heaps of wiring diagrams - this one should help you.
it is for 2 humbuckers, 2 vols & a 3 way switch.

Hi Alan,
I would use the Jazz bass wiring diagram http://www.seymourduncan.com/support/wi ... _jazz_bass
Just eliminate the tone pot.
Note that the hot lead from the pickup goes to the centre tag and the output is on the outer tag.
This is opposite to most gibson wiring schemes so that if you turn one pickup completely off, it does not ground out the other (as there is still the 250 or 500 k resistance of the pot.
You need it this way because you do not have a 3 way switch to isolate the pickups.

Thanks PJ for your input.

Jeff: You hit the nail on the head as the problem I was haiving was when I turned one pickup off it grounded out the other. Thanks for your advice and the link.

Cheers
