Schematic for H-H-H, 5 way blade, push/pull coil tap?

[DracoAran]

Guys, I looked....everywhere.

My guitar has the H-S-H configuration with a 5 way switch, one tone and one volume.

I found the diagram for the 3 humbuckers, 1 tone, 1 volume, with coil split on positions 2 and 4. That's great. http://guitarelectronics.zoovy.com/product/WDUHHH5L1101

Also, the Ibanez Jem site has the schematic for H-S-H with one volume, one tone, coil split on 2 and 4, and a push pull to send the 2 humbuckers into single coil operation. http://www.jemsite.com/tech/img/t_wd_7ct1.gif

I want to use a little 59 in the middle.
But I am getting greedy with this stuff and I want to use a push/pull pot to send all the humbuckers into single coil operation?. Is it even possible?.

Can someone incorporate that circuit into the first schematic?.

If someone is willing to work on it, I have some cheap pickups to give out.

The problem will be, that you can only "split" two humbuckers with a single push/pull pot. Although, I'm right in the middle of converting a DPDT push/pull, to a 3PDT and 4PDT. If I can get it working reliably in the next day or so, maybe I'll send you a prototype.

When I get it done, I'll draw up the schematic. Hopefully, before the week's over.

Ah, makes sense.

Re: Schematic for H-H-H, 5 way blade, push/pull coil tap?

Well, actually, how about using 2 push/pull knobs?. One to split the bridge humbucker, and one to split the middle and neck?.

It sounds feasible, but I am just not good enough with guitar wiring to design that circuit.

Allparts has a On-On-On 4-Pole 4PDT Mini Switch (12 Terminals) (EP4363-010) for USD 22. Although it's a bit overkill this one would do the job

In that case, all you need to do is this:

It doesn't matter that the volume/tone control doesn't match yours. All you'll be concerned with is the addition of that switch. The red/white combo goes to the center, and the ground goes to the top - not the bottom, as SD shows. Whether it goes to the top or bottom just determines whether the coil is split with the knob out, or in. For me, I would prefer "normal" humbucker operation with the knob "in". Thats why you put the ground to the top terminal.

Then, just do the same for both pickups.

Edit: Just to summarize: when you do a coil-split, all you are doing is shorting the red/white wire combo to either the green, (ground), or the black, (hot), terminal. If you short to ground, you're selecting the "stud" coil, if you short to hot, you select the "adjustable" coil.

How's this?. One splits neck and bridge, one splits the middle.

How's this?. One splits neck and bridge, one splits the middle.

Ok, that won't work. Here's why:

You have redundant operation in the "blue" square. In positions #2 and #4, the superswitch already grounds the red/white wires, bypassing your DPDT switch. Also, in the lower half, the bottom push/pull will "kill" the output in those same positions.

So . . . you want to eliminate the right half of the superswitch wiring. Like this:

Now, that will work perfectly fine, but whats left of the superswitch is just "ordinary" 5-way operation. So, what I'd do is . . . save the expensive superswitch for a rainy day, and just put in a normal 5-way.

Like this:

Does everything you want, and much simpler wiring.

Re: Schematic for H-H-H, 5 way blade, push/pull coil tap?

Artie, that last one is fkn aye man. If I understand it correctly, it gives me even more options, as positions 2 and 4 would give me a combination of 2 humbuckers, and the with the two pots pulled, I would get the 5 strat single coil positions.
Now, what I don't get is the switch you drew there. I am only used to seeing the 5 way switch with the 4 terminals on each side.
Is there a 5 way switch with only 4 terminals and not 8?.

he's just using one side of the 5 way...

ok, cool.

Yeah, like this:

Hey Artie, e-mail me your shipping address so I can at least send the white rw/rp single coil I am taking out of this guitar.

Also, I have another question. Since both the middle and neck humbuckers are "neck" models, is there gonna be any phase issues?. I am thinking that position 2 in single coil mode is not gonna be hum cancelling because of that as well. Would I have to install the neck humbucker upside down?.

Thanks Draco, but not necessary. I have a "box-o-pups" now, that I'll probably never use. Btw - I work Navy Avionics FLIR, (forward-looking-infrared), out here at the Naval Air Station. Got transfered from an Air Base in Ohio. (And, I work with an ex-marine who goes by "Draco".)

For some reason, I always stumble on the phase issue - fortunately, Kent S. came along, and bailed me out. (Thanks Kent.)

He's using the "other" side of the 5-way to solve that problem. What I can do is, when I get home tonight, I'll incorporate what Kent is showing into your original diagram, in order to make it a bit easier to see whats going on.

Although, Kents drawing is pretty straight forward now. (And he saves you one push/pull switch, while maintaining the same functionality.)

you can send the pickup to me for the fun of it :wink:

Hey if it's a junk pup, I'll take it and remove the poles, as a dummy coil has a wider range of use ... or seal it up in a shield for use as an impedance lowering inductor, or an in-line choke, or ... ah you get the picture ...

You're very welcomed Artie!

I took a guess that he was using a shared throw arrangement for the 2 & 4 positions ( like a standard strat), rather than 5 independent throws (like the super switch, and Fender's hot rod tele model {basically one half of the super switch}). There are about three other options to that layout also, nothing special, just a few differences. The one shown will give him 10 tones total,7 hum-cancelling, and three not (each pup alone in split mode).

Yeah man, definitely. Just send me an address.

As far as what you asked me, I can't answer people anything, even if it's something simple.
Now, what is the advantage of that capacitor hooked to the dpdt?. Is that the treble bleed mod?.

If I understand correctly, the tone pot can be wired to the volume or the jack terminal, correct?.

I don't quite get the values of the caps either. I usually see some microfarad value.

That's pretty cool. I am an E&E guy by trade, and I spent my first tour working on C-130's in Elmendorf AFB, Alaska. Now I just started working as a "specialist" on this other airplane and I have to deal with all the pointy head stuff combined. I'm crosstraining into Biomedical soon though.
I am actually driving to Texas today for my 7 level school, so I probably won't be talking on here for about 2 weeks, unless they give me web access over there.
We have an ex-marine civil service guy here too. They always have all the "cool stories".

The first two digits are "significant" digits, the third is the number of zero's, in picofarads.

So, 102 = 10 with two zero's, or 1000 pf, which equals 1uf.

I hope you can get online in Texas. We have quite a few forum bro's from Texas.

I'm gonna see if I can visit the Rio Grande shop while I am there. It'd be cool to get a Tallboy in white for the neck.
