Help .. Dann Huff diagram with OUT oF PHASE options

[dennisc130]

I'm Dennis and new here.
My search accidentally brought me to this website.
Since there is a lot of experience here, I hope someone can help me with my project and a diagram.
I'm good with the soldering iron, but circuits.. oh boy! That says it all.


It's about the following…
I have a Tom Anderson strat with this Dann Huff configuration. 
I wish to keep these Dann Huff serie/parallel sounds and like to add the following 2 sounds...


Half OUT or PHASE in position 2
bridge Seymour Duncan JB humbucker (in series)
with
Middle Seymour duncan Hotstack (in series and HOoP)


OUT of PHASE in position 4 (Brain May screaming tone)
Middle Seymour duncan Hotstack (in series and OoP)
with
Neck Seymour duncan Hotstack (in series)

Questions…
Is this possible with 1 DPDT Tonepot? If not.. with the extra addition of a super switch?
And can it be configured in such a way that when PULL UP (activated OoP or HOoP) the PUs are automatically in series. That the series/parallel toggles would be over-ride.
So MID PU automatic is in OoP or HOoP in position 2 of 4, and the other position are 1-3-5 are standard in series.
Can someone add me a diagram?

Thank you in advance, because without a diagram/drawing I will never succeed.
Good day,
Dennis…

Hello and Welcome to G-Nutz2!

Is this possible with 1 DPDT Tonepot? If not.. with the extra addition of a super switch?

There are others here who are more clever than I am. Whenever I say it can't be done, often someone proves me wrong. But I don't see how this could be done with just a single DPDT. Switching phase occupies both poles of a DPDT, but you not only want to swap phase, you want to add a cap in one 5-way position but not the other. Seems to me that would require at least one more pole on the switch. With a Superswitch? We'd have to look at that, might be possible.

And can it be configured in such a way that when PULL UP (activated OoP or HOoP) the PUs are automatically in series. That the series/parallel toggles would be over-ride.

I strongly suspect that this would also require more switch poles. Are you open to using the Fender S-1 switch? At a glance here, I'm thinking a Superswitch and an S-1 would be the minimum switching reqwuired, but let's let others weigh in. If it can be done, we can work up a diagram.

Also, just thinking aloud here, if you were willing to lose the series/parallel switch for the middle pickup and convert that switch to a middle phase switch, things would be simplified considerably.

Thanks for the replay newey,

I don't like the quality of the Fender S-1.
If the phase can be activated with 1 DPDT tonepot , and then with a super switch or Oak Grigsby 2-pole 5-way or Schaller Megaswitch...
for the cap and HOoP I would be very satisfied.

In the worst case... 
I would be very satisfied with just the extra position 4 (Brian May Neck/middle Out of Phase tone)
automatic activated  when DPDT Tone PULL UP, without losing the other Dann Huff series/parallel circuits.
Anyone who can help me with this?
I appreciate every input

I strongly suspect that this would also require more switch poles.

Many more: two per each series/parallel toggle, plus another two for switching the middle (H)OoP — so eight in total. Thus making this part of the idea pretty unworkable, 8PDTs do exist but aren't likely to fit: push button variants being way too deep; and slide versions having roughly the same footprint as a 5-way selector switch (approx. 50mm × 10mm).

We can wire the phase switch such that it always adds the capacitor, then use a pole on the 5-way short that capacitor. As it stands there is currently a spare pole available on the regular Strat switch, which can get us most of the way there.

In the following diagram the 10nF capacitor is added in series to the middle when flipped OoP: in position 2, this gives the B + M HOoP option; and in position 4, the previously unused half of the 5-way shorts that capacitor giving N + M OoP.

The slight quirk comes from position 3 (whilst the middle is OoP), the capacitor is still in the circuit and thus acts somewhat similarly to a 'strangle' (bass-cut) capacitor as you'd find in traditional Fender Jaguar wiring. However, with being quite a bit larger (10nF here, versus 3nF in a Jaguar) the effect would be more subtle. With an assumed amp input impedance of 1M in parallel with the 500k pots that equates to a cut-off frequency of 79.6Hz (just below the low E of standard tuning, at 82.4Hz), so likely only a very minor difference compared to the middle pickup with the capacitor removed. It'll only become more apparent if there's a greater load 'downstream' in the circuit, the classic example being a pedal with low input impedance (e.g. vintage style fuzzes or treble boosters), but it does also include the guitar's own tone control. That is, when the tone control is lowered, it will not only cut treble as usual, but will also cut more bass — leaving a more mid-focused sound.

To be clear, this would only affect position 3 and only when the middle is flipped OoP. The potential issue could be avoided by using a superswitch, but personally I don't think it's that much of a problem that it would be worth swapping out the switch.

Wow… Yogi B- beautiful layout!

if I understood it correctly…

1) Activating directly so that series/parallel are overwritten requires too many switching poles and is unworkable.
2) OoP and HOoP with PULL UP tonepot gives a 'quirk' in position 3.

I would have liked to keep exactly the original sounds series/parallel with 3 mini toggles... also in position 3.
So HOoP with cap on DPDT tonepot is not an option.

Question…
Can the HOoP with cap be installed on an Oak Grigsby 2-pole 5-way switch (or 4-pole or superswitch) to solve this problem?
So I get this in yellow?

I really appreciate your input.
Actually, I also wonder which program you use to create such great drawings?

Yes, with a 4-pole or superswitch, like this:

(Since you mentioned Schaller the Megaswitch, the Megaswitch M would definitely work since that's just a 4P5T switch like the superswitch. I think others, such as the 3.0 versions of the Megaswitch S or Megaswitch E, could work too — but a 'full' 4P5T keeps your options open if you ever decided to change the wiring in the future.)

Microsoft Visio. Over time I've redrawn my most commonly used shapes, but the shapes are heavily based on those created by the Guitar Stencils Project.

Hey Yogi B..
Again beautifully made. I appreciate this greatly.
I have Schaller Megaswitch S... but I have no idea how those Schaller connections work.

I'll try your schedule with superswitch this weekend and let you know,

Thanks for the info Microsoft Vision... the fact is ..its useless  if I don't always understand the diagrams
