Help with HHH - Dual Coil Splits, Phase, Series

[frets]

Hello Angels,

I’m still struggling with this concept of an HHH that possesses the ability to
Dual Coil Split, Phase and Series on 3 push pulls.  I am EMBARRASSED to say that I can’t figure this one out.  I never build HHH guitars (they don’t sell); but, decided to do one.  It’s been sitting in my shop for months without a harness.

I may not go with the idea of an HHH Dual Coil Splits, Phase, Series. -  but at this point it’s become an obsession to figure it out.  My lack of wiring experience with HHH setups and my need to understand more advanced designs has me at this crossroads of this extreme frustration.  


I present two diagrams. I’m looking at a Volume with Two Tone pots that would allow the guitarist to have 22nF or increase it to 44nF. I know that they both are wrong.  I ask that whichever is closest be examined with some remedies.  I don’t care about what phases what or which series which.  I just want one to work. Please oh please🥺🥺 sez Cindi Loo Hoo!!

I just noticed that I failed to make a Volume on the 2nd one.  Boo Hoo Hoo  😭😭😭😭😭

Sorry I had to move this thread from schematics, since this isn't finalized yet.

I haven't had the chance to go through both diagrams (IRL work is calling . . .), but several points:

First, in the first diagram, the middle coil split won't work because the "series junction" at the P/P switch isn't connected to anything.

Second, the wiring for the tone pots is funky. You show potentiometer wiring (all 3 lugs connected) for both tone controls rather than rheostat wiring (2 lugs only are connected), which is the standard way to wire tone pots. I have no idea what wiring tone pots like that will do, but I doubt they will operate the way you want.

Again, on the first diagram, let's look at the neck tone pot. Your components are shown upside down (as is preferred, since this is the way we wire things). This orientation puts the CCW lug to the left. We have signal from the volume pot, via the fuchsia-colored wire, going to the CW lug of both tone pots. This will result in left-handed operation. But for the neck pickup, you have the black pickup wire going to the CCW lug, so you have "hot" input to both sides of the pot. Not sure how that is going to work.

I'm not clear on what you are trying to do with the tone pots. Are these to be individual neck and middle tone pots? (This is suggested by the neck pickup black wire going straight to the tone pot). Or, is this some sort of "dual master tone pot" arrangement? (suggested by both being tied together).

Two things that would be very helpful to folks reviewing these diagrams. First, post a "truth table" detailing the various switch/pot combos/functions you intend, so that we don't have to guess at what you want the end result to be. Second, your (very detailed and nicely drawn)diagrams shows the bare-wire pickup shields as dark grey wires. These are all appropriately shown as being grounded to switch frames, etc, but their inclusion makes the diagram harder to follow (we have black wires from the pickups that look similar, light grey wires from the pickups substituting for white wires, plus these dark grey shields- TMI!). The Shield wires can be omitted as understood, they don't affect anything in your wiring scheme and we all know they will get grounded in some fashion in the actual wiring.

If the tone controls are just meant for the neck and middle pickups- Strat style- you can either wire them off of the 5-way switch as on a Strat, or wire the tone pots "across" each pickup, as on an LP. In that case, the tone pots are "first in line" after the pickups.

OTOH, if you are intending some sort of "dual master tone" thing, we need to talk. Unless you are using no-load pots, having two pots in the circuit will dull the tone quite a bit, and you'll have interaction between the 2 pots. And, in any event, I can't figure your tone pot wiring either way.

Dearest Newey & Other Angels,

Here was my warped logic. I’m fine with HH setups. Can wire most anything with those. So, I applied HH setup configurations to the HHH. In particular, attempting to mod HH 3-Ways to an HHH 5-Way.


I was trying to go with cumulative tone pots to get 22nF or 44nF. I’ve taken out the cap on SW3 in both diagrams; although, I hate having a pot just sit there as a switch. Wish that pot could do something + plus it’s switching effect.

I went ahead and tried to update - attached are Trial 2’s. Again, I appreciate any help and understand it is a busy time of the year.

I can’t find one diagram that deals with an HHH Double Coil Split, Phase and Series.

If it’s confusing to have two diagrams, let me know and I’ll dump one.
Thanks
