Humbucker Series/Parallel with Spin-A-Split Mod

[frets]

Hi Guys,
I was looking for this mod online forever and could not find it.  I had it archived in my notebook and am posting a modified drawing of it so that guys searching on the internet can find it.  It’s a great mod.

frets, you title this mod, ‘Humbucker Series/Parallel Mod with "Spin-A-Split"’; you say it’s great; but, does this mod to a pot make a humbucker guitar playable with humbuckers in Series or Parallel?

And what type of pot is that?


Hmmm… after thinking, does this mod cause humbuckers to be in series when the pot is at min or max; and then spinning the knob would cause the humbuckers to split into parallel?

I’m truly sorry if these are dumb questions.


EDIT: 😱 my stars are blue! … I’m past sir reTrEaD. 🤪

If you read the circuit!
It is a series to parallel switching system

The puzzle is what the pot does,
When in series it is a added resistance around the south pole
I say added!!
1/(1/Pot)+(1/Pickups DC Resistance)
So will lower it a bit


Have to link me up with
John S Atchley and Drew Parker's oriental links about this

------

Just thinking
Dual Stack Pot
+N to Output, -N to Lug2a
+S to Lug2b, -S to Ground
Lug3a and Lug3b Linked to each other
Lug1a Ground, Lug1b Output

One way will give you Parallel with the value of the Sum of the Wafers of the pot (IE if 250K will be 500K)

Other way will give you Series with the Pot in the middle to Ground/Output
250K around North and 250K around South

I'm not 100% Sure of what the middle would look like, or even 1/4 and 3/4

Thank you @angellahash! 👍😀

That seems really cool!

This circuit also seems cool:

note that the only difference between the 2 circuits, is the switch itself.

the switch on the left: DPDT ON-ON-ON,

the switch on the right: DPDT ON-ON.

UnklMickey’s is better in the fact that the signal volume is not reduced in series mode, as you stated describing the “Spin-A-Split”… right?

But, it can be worse bc we don’t understand what pot rotation to 1/4, middle, and 3/4 would sound like; and UnklMickey’s only either makes the pickups in 100% series or 100% parallel (the diagram on the right).

Well Mickey's is the same just wires in a different place
The other one is an on/on/on and wouldn't work as this is a push/pull on/on


I didn't state any thing, apart from read the circuit.
Question where are you from?
Gotta be honest you sound like your talking about some thing else.
I'm a bit scared to post, for I think it will confuse you. I can see how you got so many posts

Sorry the circuit you have shown doesn't use a pot! Just a basic standard switch.
Just what Fretz has done.

In series the resistance changes
You do seem very excited about Mickey's, to the point of hmm scary!!

Hmm… yes, it’s fairly obvious that Mickey’s only uses a basic standard switch.

Sigh, sry, I wasn’t aware that the circuits were similar and that frets’ pot is a push/pull; thank you.

So Fretz can do NxS, N+S with the switching
The Pot also let's you do N on its own
I think if you wanted S as well

Dual pot but one side the wafer is cut let's call it Lug1, so where the Neck comes in to the switch and the switch goes to ground, this changes to Lug2 with Lug3 going to Ground and Lug1 to Output ( with it being cut it is away from the circuit)
So get N+S or S depending on the Pot
And NxS or N depending on the Pot

Guess could so it one wafer
Lug1 to output and cut,
Lug2 to -N
Lug3 to Ground

Meaning all the way to Lug1 S
All the way to Lug3 then
