I need help with HSH super switch wiring

I have these questions about the tone wiring and treble bleed for the volume.

JohnH recommends a 150K resistor and a 1nF cap for the treble bleed, which comes after much experimentation by him. Although, IIRC, that was with single coil pickups, not sure if he uses the same for HBs.

What is your question regarding tone pot wiring?

I just notice the Ibanez V7 pickup has only 3 wires. The coil tap comes using only one wire, so it seems there is no way to follow Retread wiring diagram.

What cap he suggested and the wiring from the out to the volume and tone, but I could take that part from another diagram no problem

Yes, that will present a problem. Off the top of my head, I think you would, at a minimum, have to lose the ability to split to the other coil of the neck HB at position 4. This will take some work, so don't go wiring just yet.

parallel neck position would not be possible. I'll remove the pickups tomorrow for a better inspection, from my research it seems that the V7 should have 4 wires, but my guitar is from 2000 and maybe the missing green wire could be present on newer versions.

[newey]

Typically, pickups with just one wire for coil splitting actually have two, just combined into one wire right at the pickup. The wires there are likely very fine, and trying to separate them may end up destroying the pickup.

And, you're right, the parallel neck setting won't work. I missed that.

thanks newey, I'll have another job to be made on those pickups, swap the magnets between them, I'll check them carefully to find out about the missing wire while I do that job.
I'll think about swap them for better pickups later if the fourth wire is missing. This wiring has the best of both worlds IMHO with just on additional switch.

I got two SD humbuckers, I finally will try the wiring today.

I have good news and not so good news.
The wiring works as it should. Thanks for the schematics.
The bad news is I am having issues with ground loop. My guitar is shielded with copper tape. When the humbuckers backplate touch the tape I got now signal. AFAIK it should not behave like this, since it is all ground.
I need some help, what am I missing?

Just to let you know, I found the issue. SD humbuckers have a 5th ground wire and it was terminated with the green positive.

Hey guys, I never got to actually putting this together as I didn't get the switch in time so I just put the coil split on mu standard HSH wiring. This experience made me realize that split humbuckers on their own can be hit or miss depending on the pickup and that I really don't need one in the bridge. I actually began to respect HSH for what it is as long as you have a way to get some single(ish) sound in the neck.  I also figured that changing two split humbuckers position from inner to outer coils might be more tele like on my 22 fret guitar. 
I found Schaller Megaswitch M in local store which is essentially 4 pole 5 way switch and I am ordering Bourns pots as they actually have a push-push. And here comes my latest iteration of HSH/SSH/HH mashup:



Like I said, depending on the neck pickup, the "neck single" sound might sound better with either split or parallel, it is an easy change in the wiring (in blue), providing the wiring is correct. I edited a diagram from DiMarzio site so I used their color codes as well:


I am planning of going with Ibanez style electronics, linear 500k volume pot with 330pF cap for treble bleed and log 500k tone pot with 22nF cap. What kind of tolerances I should be looking for when buying capacitors for guitars? 10% or better?

Bourns pots have 20% standard resistance tolerance se maybe there is no point in looking for better caps

Can you please check this one? If everything is correct I will try to make a diagram for Schaller megaswitch
Thanks!

Your diagram looks good to me.

That raises an interesting question: In terms of the degree of variation from the stated value(s), would we likely hear the difference if two pots varied by 20%, and would we hear the differences if two caps varied by that percentage.

Is there a way to make this work with a stacked hum-canceling pickup in the middle? I'd be hoping to have the middle pickup operate as a stacked humbucker in position 3 (with switch down) but split to only the top coil in positions 2 & 4 to cancel noise when combined with the neck and bridge splits. I'm using a Fender S-1 switch, so I'd have a 4PDT to work with instead of DPDT, but I can't quite figure out how it could work since all the superswitch poles in positions 2 & 4 are being used. (My failed attempt at something similar is in this thread.)

Speedwagon-

If I didn't give you a proper welcome previously, I apologize:

Hello and Welcome to G-Nutz2!

We're still in the process of trying to help Josip get everything sorted with his mods, and while your questions are indeed related to his thread, I ask that you re-post your questions in a separate new thread in the Guitar Wiring section. More people will likely see your post there, even if they may not be following this one; also, the discussion of your proposal may get somewhat lengthy here, derailing josip's scheme.

So, please repost it separately.

Oh, and, Speedwagon-

All I have to say is: "I believe it's time to eat a fly . . ."

No problem - I started this thread a few days ago but didn't get any replies yet, so I'll maybe post there explaining the overlap with Josip's diagram/project to clarify: guitarnuts2.proboards.com/thread/9491/hsh-diagram-noiseless-pickups-help

It is finally coming together I decided on DiMarzio Super Distortion (bridge), HS-2 (top coil only) and Bluesbucker (Nect) and got them with original Ibanez VLX91 switch, pots and caps. This is my final iteration, just to check it with you guys before the guitar goes to a tech for wiring and some fret dressing.



Here is the switching diagram:



And here is the wiring:



All the positions involving two coils in parallel should be hum-canceling, nothing should be out of phase. Tone pot is push-pull and switch is VLX91 but I used components I had in the tool, everything should be clear, hopefully. Wire colors should be accurate, white and green wire from HS-2 are not used.

Does it look OK to you guys? Thanks!

[josip]

Finally done, works perfectly 

[newey]

Sorry no one got back to you on verifying your diagram (I just verified it before I scrolled down to your latest post, saying you'd already wired it. It is correct, and you've proven it). But this has been a long project, glad to see you got it up and running!
