I need a diagram for one humbucker/2 push-pull pots

[kyolic]

On my guitar, I have a JB Junior on the neck and two push pull pots (1 volume - 1 tone).



I need one push pull pot to switch the pickup between series-parallel and the other one to switch it between series humbucker-single coil (coil split).



I searched on the internet however wasn't able to find a diagram for this. Any help is highly appreciated. Thanks in advance.

Hello and Welcome to G-Nutz2!

I think this will do it, but let's get another set of eyes to look at it first before you start wiring. A couple of things to note: First, I have omitted the Vol and tone pot wiring for simplicity, and I don't show the entire push/pull pots, just the switch portion. But you can consult virtually any guitar diagram with a single Vol and Tone for the rest of it. Also, this is done with Seymour Duncan wire colors; when in single coil mode, the North coil (Black/White wires) is the active one. (If you would rather have the other coil active, that can be done, but if this is a single pickup guitar, it probably won't matter which coil is selected). Also, the white wire is shown in grey for visibility.

the other one to switch it between series humbucker-single coil (coil split).

As I've drawn this, the coil cut switch (SW 2) will give you single coil operation regardless of whether the series/parallel switch is set to series or to parallel. So, if you are in single coil mode, the series/parallel switch doesn't do anything- you get the North coil only either way. If the coil cut switch is "off", then you have both coils, in either series or parallel, as determined by the series/parallel switch (SW 1).

I think that having the coil cut switch operate only when the pickup is in series can be done, but you would have a dead setting if SW 2 is set to coil cut and SW 1 is set to parallel. So, it seemed more logical to do it this way.

Newey thank you very much for drawing the diagram. I can't thank you enough.

I will have the guitar wired by the tech in a couple of hours. Do you think I should tell him that this is the %100 correct wiring diagram?

kyolic,



Hi, and to The NutzHouse!


You can tell your guitar tech to go ahead, newey's done a bang-up job.

Thanks for the warm welcome Sumgai. Now it is awesome to know that this will work perfectly. Thanks a million guys!

No, you're reading it right. The coil cut switch always cuts to the North coil, no matter the position of the other switch.

I saw this yesterday which allows seperate usage of north and south:

Newey would it be too much if I politely ask you to draw this for just one humbucker like you did before?

ky,



Using your current parts, if you want to have both coils available independently in single-coil mode, you will need to use both p/p switches. Accordingly, you must either give up the OoP option, or install a third switch somewhere.

Optionally, you could install a more complicated switch (such as a Fender 2P4T switch like those found on the Baja Telecaster) that will give you all four options in one switch (Coil 1, Series, Parallel, Coil 2). Well, all but the OoP function. If you want OoP on just one pair-combo, then a so-called "half Superswitch" 5-way switch will work to give you that option, for either Series or Parallel, but not both. To have both options (SOoP and POoP), you will still need a second switch, such as a p/p or mini-toggle.

Now, if you are asking for my opinion, I'd have to tell you that the two coils, when selected individually, won't sound very different. Maybe slightly different when all else is quiet, but when you're jamming with other players at volume levels louder than a whisper, then any difference won't be audible.  IMHO, of course.

You're misreading ky's original request. There was never any OOP option. But you're right about the need for more switches to get both cois

I'd be happy to do it, if it would work. But there's no series/parallel switch in that scheme, it uses two separate push/pulls for the coil cutting. As sumgai notes, you'd need more switching to be able to get a choice of coils to be cut. And also as sg noted, not much difference in sound unless the coils are very dissimilar.

Better be careful with that '12tone - import 3-way diagram', it looks too clever to be right! (given that we didn't do it, and neither did Phostenix - ie, it suffers from NIH syndrome (Not Invented Here))

Seriously, it may be inherently clever, but it has at least a phase problem. See how the bridge pickup has it's green wire grounded and the neck pickup has it's red wire grounded, full time? These wires, in SD colours wired normally, are respectively on the ground and hot side of the relevant coils, so they shouldn't be both grounded, given that a normal in-phase combo of both humbuckers is a required option.

There's the daily puzzle for those interested to solve it!

[JohnH]

I've had guitars where you can choose which single coil from the bridge humbucker. They do sound slightly different as single coils due to the position relative to the end of the string. But, splitting a humbucker often tends to a thin not very powerful sound, so of the two, I'd always want the coil furthest from the bridge for a bit more weight. Also, sometimes the slug coil is stronger than the screw coil, so would rotate the pickup so slug is nearer neck.

newey,


Oops (couldn't help it!), I did miss the boat on that one. Apologies to all.

ky,


That's three of us who have gently advised you that splitting for the two different coils in a single pickup is not really worthwhile, tone-wise.

However, since you've asked, try this on for size:

Here's the Truth Table:

Both Down = Parallel
Both Up = Series
S1 down, S2 up = North on, South off
S1 up, S2 down = North off, South on

This is an adaptation of something I did a long, long time ago, originally for two Hb pups.  Sadly, very much so, the diagrams I had posted back then are now null and void, no thanks to Photofuggedit.  We're working on getting things back in order, but one of our Staff members is on holidays, so it may be awhile before the project is completed.

Note to other modders:  This can be easily adapted to other layouts, including two full humbuckers, two single-coils, etc.

Further note: newey will gladly remind you (one and all) that this is nothing more than a dude'd up Binary Switching scheme... and he'd be correct.

Sumgai thank you very much for the schematic. I will ask the tech to wire it like that. Highly appreciated.

ky,



You're welcome! And don't forget to post a sound clip when the rig is all finished.

kyolic,


If there's still time before your tech heats up his soldering iron, let me point out that I've updated the diagram, above. It's nearly the same, except that I was able to eliminate the so-called "hanging hot" issue. Ask us, if that's not something you're familiar with.'

It looks to me as if the North coil will still be hanging when the South only is selected.

This needs vetting but I think it will work without any coils hanging:

[kyolic]

So which one should I use?

Both ends of North are going to the output (labeled as To Controls) when South only is selected.

BTW, I like the way you depict the two switch positions.

Either one, they both work as intended. What you're seeing here is proof that for most wiring setups there are at least two ways to do it, and probably more.

My drawing may look simpler, but a closer inspection will show that reTrEaD uses only one more terminal than mine, and that does the job of connecting North Start to the Output only when needed.  Crafty, I hadn't thought of that.

Your call (or your tech's call, if he has an opinion).

Ok I provided the tech both diagrams and the job is done perfectly. Now I can use my JB JR as Serie - Parallel - North Coil - South Coil. Thank you very much for the help guys. Highly appreciated.
