2 Split Coil Pickups In One Guitar

[rightd27]

Hello. I have an idea but I’m not quite sure if it can be done. On my LAG I have a single coil in the neck, a single coil in the middle, a humbucker in the bridge, 1 volume, 1 tone and 1 5-way blade switch.

What I want to do is to put a single coil sized humbucker in the neck and coil-split it where when the knob is kept down it’s a humbucker and when pulled up it is a single coil. And of course this would go to the 1 new push / pull volume knob which I install to eliminate the stock volume knob that came with the guitar.

This is where I am not sure if what I want to do is possible.

The existing middle single coil I am not replacing or coil tapping. I want to keep it as is. I will need to know how to wire it however.

In the bridge I want to coil-split the humbucker with the default position being the knob depressed and keeping it as a humbucker and pulling it up changes it to a single coil. However I want to eliminate the existing tone control and replace it with the bridge’s own the push / pull volume knob.

On one of my guitars there is a humbucker in the neck and a humbucker in the bridge. I rewired it to where the tone knob was converted to it being the neck pickup’s own volume knob.

1. Can this whole adventure be done ?

2. If this can be done, how would I wire the middle pickup ? Mainly I just have the bridge humbucker active when I am playing something with a lot of gain. Mostly metal / rock. But clean I use the neck and middle pickups. For me a clean humbucker in the neck and a single coil in the middle both active is sweet as sugar. Especially with a nice reverb, delay and chorus.

3. If I have come this far I might as well throw in a switchable treble bleed with a slider switch for the bridge pickup only.

This one guitar will basically be able to give me any tone that I want to dial in. As it stands right now it already has an external Roland GK-3 midi pickup.

Thanks for reading this very long post. I wanted to be as precise as possible in explaining what I am looking to do.

Just breaking down what you are asking

First Point the Push/Pull Switching.
When drawing circuits tend not to say whats one state or another, thats up to you 
Saying that ... as you look at the Legs POKING out, middle is the common every side
Top 2 pins are the UP state and the Lower 2 pins are the Down (Normal)

UP A	UP B
COMMON A	COMMON B
DOWN A	DOWN B

HSS Guitar.  BUT changing it to a HSH (just the xxH being a single coil size)
hmm so 4 wires coming off this NEW HUM, and I've not got a clue of COLOURS used to know what is HOT and what is NOT  (always someone who using another colour just to pee off the rest) 
So Top + Top - Bottom + and Bottom -. 
Typically the Bottom - goes to GROUND
UP A = Bottom +, COMMON A= Top - and DOWN A=GROUND
<SINGLE when down and Humbucker when UP>
Top + going off to the 5 way Switch, replacing like for like

Volume,   Lug 1=INPUT, Lug 2=OUTPUT and Lug 3=GROUND


And for the Humbucker that is already there, its just the other way around
UP A=GROUND, Common A=Top - and DOWN A=Bottom +

Tone, Lug 1=Input Line, Lug 2= Input Line and Lug 3=To Capacitor.
can also do it Lug 1=Not Connected, Lug 2=Input Line and Lug 3=To Capacitor.


1. Yes, but I'd sooner change a stage at a time (i always muck up when doing the whole thing in one go) 
{like taking out peoples organs, if you take all out they start to scream but a bit at a time they might not notice}

2. If this can be done, how would I wire the middle pickup ? Shouldnt need to Touch the Middle Pickup !!

3. If I have come this far I might as well throw in a switchable treble bleed with a slider switch for the bridge pickup only.
hmm Treble Bleed to me, goes around the Volume! lot of different types out there. 
So, we are going to use Slider Switch for being in the Treble Bleed  when in BRIDGE ONLY
So depending on what type of 5Way switch you got 4P5T, 2P5T and there is a strange one, i dont even know what to call it (longer arms that move over to output/input pegs) and you got the Cheap S-Type

I can only think of how to do it on the 4P5T and the S-Type for BRIDGE ONLY.
4P5T you only need two of the poles to use as a Selector and just use one pole to bring this bleed in, Common as the  Bleed and the Bridge point as the Bridge.

The Cheap S-Type, is a bit more complex as its a HACK.
Means taking off the board and cutting a Track, for that i would Cut the Track for where PIN 3 goes  (This will be Position 4 and 5 cut between so that only when Bridge is selected the Bleed will come on), PIN 4 to Bleed
PIN 5 OUTPUT, PIN 6 NECK, PIN 7 MIDDLE, PIN 8 BRIDGE

>Very wordy and someone might do a bitter image than myself <

I think you are asking for some thing like this.>Typical ME!, 1am, the DD 1)NH 2)NHM 3)M 4)MB1 5)B1

Hello and Welcome to G-Nutz2!

'bunny is correct as to the layout of the DPDT switch that you will be using on your push/pull pots.

So, correct me if I've got this wrong, but you're wanting:

1) A P/P pot to split the neck SC-sized HB. Presumably the pot would serve as the volume for the neck pickup.

2) A second P/P pot that will replace a tone control and serve as a volume for the bridge HB, and when pulled will split the bridge HB to single coil. So, two pots, 2 volumes, no tone?

3) A slide switch to switch a treble bleed circuit in/out from the Bridge volume pot.

I haven't worked this out yet, but I think it can all be done. My only question mark has to do with integrating the coil split switching with the existing blend control. If you have a diagram of how this is wired now, that would be helpful.

Several points:

I have said this before, and don't let me discourage you from trying this yourself, but I had lousy results splitting the coils on a SC-sized "dual rails" HB, since the individual coils are so much smaller than a regular HBs coils are. But by all means, try it and see what you think. In my case, the volume difference when split was too much of a drop.

If you want to do so, you could have a single P/P pot split both HBs at the same time. Again, I say this subject to possible issues integrating the blend pot.

You will want to preserve hum-cancelling between the N and B split coils, meaning you will want to split to one North coil and one South coil. Since your pickups differ, some testing will likely be needed to discern which is which.
