Screw Coil Spin-a-Split

[born2defy]

If i wanted to wire an unused pot as a spin-a-split but I wanted to ground out the stud coil and leave the screw coil instead, how would I wire the pot?
Would I still have to ground one of the terminals or would I only have red/white and hot on the pot? Also, would that hot lead then feed over to the volume pot?

Yes... oh, what was the question(s)?

Two ways to do this. The easiest way if you've already got the humbucker wired the "normal" S-D way (green/ground, red & white series connection, black/hot) is to use the pot to gradually short the black & the red/white series connection. That will short out the slug coil. And, yes, the pot lug the black lead is connected to should still feed to the volume pot (or switch, depending on your circuit).

Hope this helps,

P.S. Chaos just explained the other alternative.

To clarify Fresh Start’s post, you short the red / white connection to hot (black) not ground.
The other way to turn off the fixed stud coil is to wire red to hot, white to ground, connect black and green together. Shorting black / green to ground to split.

Like this?

That looks good, but you want the red and white together on the center lug. Leave the other lug of the spin-a-split pot blank. (The right-hand terminal in your drawing.)

Thanks, Artie. I concocted a schematic for the series/parallel/twin spin-a-split/both pickups in series/tone-bypass idea, but it is far too convoluted to post. I'll throw it up here once I clean it up a bit...

I love convoluted wiring diagrams.
