ALTERNATIVE WIRING FOR PARTIAL COIL CUT. THEORY InPUT APPRECIATED

[Jack_TriPpEr]

Hi GString,

I've continued to ponder your wiring ideas, and I have a question. When you combine two coils of the same humbucker pup in this way (in parallel but with one coil partially cut), i would suspect that the resultant sound could have some Strat Position 2 type quack present? Of course, the amount of quack would depend on how much the 2nd coil is cut, i.e. the value of the resistor. Would you mind letting me know if my suspicion is correct and what resistor & cap values seemed to produce the highest amount of quack?

Member Gstring did reply to my last question above but under a different thread. I am copying that reply here for anyone else that was following this thread.

Although his response of "cap and resistor in-series *with the pup*" (emphasis added is mine) raises concern that he might not have understood that my question was asking about a cap & resistor in-series *with an individual coil from a humbucker wired in-parallel*, which is the innovative wiring scheme concept he outlayed earlier in this thread.

Gstring: "As regards getting more 'quack' from a SSS Strat using resistors and caps in series with the pup, this is something I have never experimented with and am not sure if experimenting would produce results of value and there would probably be wiring issues unless it was accepted that the mod was permanently connected. I gather you are experimenting with this so don't let my comments put you off."

Sorry for not responding, I've been away from the forum for a while. Like Artie, I've got lots of irons in the fire... just moved recently so I've been busy setting up my shop, working on several custom guitars and custom compensated nuts and bridges orders. My paint room isn't quite finished yet so I've been working around that problem as well. But it looks like Artie and Jack have things under control and will give you the best advice that you can get, so I will defer to them.

Very interesting concept you're working on. IMHO, the subtle change in sound you'll get from all of this complexity won't in reality be noticed by anyone but you. But the learning that you obtain from working through all of this is probably priceless. Good luck.

Freefrog, sorry to hear about your mom. Mine just passed away two weeks ago (at 99 years old) which in some respects is a bit easier to handle than what you're going through (and will be going through). Best wishes to you and your mom.

GuitarDoc,

Glad to hear from you and that you are well.

You're absence has not gone unnoticed here - you have been missed here.

Congrats on your recent move and having a new shop to set-up. Sounds exciting.

My condolences on the loss of your mom.

Thx Doc, and all my sincere condolences...
Mum is getting better for the moment but the medical context is still there with its weight and exigences. That's life (and it also makes my presence here a bit "erratic").

I wish you all the best with your renewed shop and new guitar projects!

@ Jack_TriPpEr: my current on / off mode doesn't ease communication but feel free to call me if I can help in any way.

Thanks Freefrog,

Do you happen to know if Strat Position 2 like "quack" could be a possible sonic result from partially cutting one coil of two coils from the same humbucker that have been wired in parallel? I do understand this would be highly dependent on the degree to how much the 2nd coil is cut/sent to ground.... as well as any cap placed in line and its value.

You're welcome.

Regarding your question: in my humble experience and opinion, the result obtained by tuning such circuits really depends on the pickup(s) used with their distinctive inductance and Q factor.
Now, what you want should be reasonably approximated by a "fat tap" wiring involving a low value cap (4,7nF / 3.9nF / 3.3nF / 2.7nF / 2.2nF... adjust to taste in order to obtain a dip @ +/- 2khz).
It might be interesting to try with a Custom hybrid - and with the SH1 coil filtered out while the stronger Custom coil would remain enabled...
