Les Paul push pull that’s not from the Page playbook

Most guitar players don’t get the most sounds out of what most humbuckers have to offer. Jimmy Page got around to it in the 80’s. Story is he had some engineer design a switching system for his Les Paul using four push pull pots that incorporated coil splitting, phase reversal, and one pickup running in series into the other.

I recently had a customer come in with his Les Paul for a pickup swap because his current tone wasn’t squeezing anyone’s lemon.  He also asked for phase switching and coil tapping without naming he who has two necks. Since I only rely on the internet in matters of love I didn’t scramble for existing wiring diagrams, instead opting for a pen, notepad, and an amount of free time only an underemployed guitar tech has in the middle of the day.

I pride myself on my switch skilz. Jimmy can afford to pay an engineer to draw out this complicated scheme. I imagine a degree in such things will get you the result much quicker than I did. Point is I did it without a single class in electrons. And here I offer you a class in electrons. Or guitar switches. Yea, forget electrons, you don’t need to know about those to understand basic guitar electronics.

Push Pull circuit

This is the mess we’re dealing with. Each push pull pot is a DPDT switch. Double pole double throw means that there are two independent sections that can be in two states. There are four switches total, each with two columns of  three tabs. The teal lines represent the switch wiring tabs. The center row is known as the common. The common tabs will be connected to either the top or bottom rows depending on the switch position. The green lines are the potentiometer tabs. These control the volume or tone or whatever else you wire them to do. I don’t know about those other symbols, I just think they look cool.

So how do you wire all this to two humbuckers with four leads each (five including ground wires) to coil tap and reverse phase keeping in mind the goal that each switch state should give a unique sound? First draw the above as your starting point, connect the wires where you think they should go, then draw a subsequent diagram for each switch state and follow the electrical path all the way through to ensure proper functionality. Basically it’s just trial and error. LOTS of error. So best do it on paper.


Took several iterations but it’s better than burning up the switches trying to get it right. To explain the end result I’ll first explain our goal. It was not to copy the Jimmy Page wiring. While each humbucker does coil tap and the bridge reverses phase in relation to the neck, the neck reverses phase of one of its own coils while running them in parallel. Page opted to run one humbucker in series to the other. My tweak with the neck coil phase reverse gives you a very pinched, low output sound but with a bit of a boost can yield a great funk tone. Sonically as far as you can get from the wooly, slightly muffled tone the humbuckers in series with each other will give you. Here is the final drawing.


The green and black leads had to be reversed on the neck circuit to get everything in phase with all the switches in the down position but the drawing gets us where we want to be. Let’s start with the bridge. Reversing phase is easy, this is done on the bottom left switch. The left common tab gets the black lead. This allows us to change its path to ground or hot. Hot goes to the pots input, ground is ground. You see the “X” pattern connecting the hot of the 1st tab going to the 4th tab and the grounded 3rd tab going to the 2nd tab. Connecting them in this way allows the poles of the switch to be on opposite sides of the circuit no matter the switch state. That is, when the commons are connected to the bottom row, with tab 2 being ground and tab 4 being hot, the left common is going to ground and the right common is going to hot. When the switch is in the second position with tab 1 being hot and tab 3 being ground this sends the left common to hot and right common to ground. It’s important to make clear again that the common tabs in the middle are connected to either the upper or lower tabs depending on the switch state.

This alone does not achieve phase reversal as the other pickup leads are connected to the second switch. By connecting the 2nd common of switch 1 to the 1st common of switch 2 we allow for the 2nd common of switch 2 to change states in sync with switch one. This means that regardless of the state of switch 2, the phase will still be determined by switch one. When in the down position (state 1) switch 2 common 2 is connecting the green lead on tab 2 to hot. The “R/W” is the red and white wires together connected to tab 1 of switch 2. When in the down position they are not connected to anything but themselves allowing current to flow from the green/red coil to the white/black coil.

Following the signal path while both switches are in the down position we start at ground, follow from tab 3 switch one to tab 2 of switch one, up to 1st common to black lead, through the first coil to the white lead then on to red lead, through second coil to green lead, up to switch 2 common 1, to switch 1 common 2 to tab 4 up to tab 1 to hot. Which looks like this:

Push Pull flow

Ignore the bad ms paint job. Use this approach to figure out how each switch state will allow current to flow. I’d make a diagram for each path but that would take as long as wiring the thing in the first place and I’ve spent enough time on this article already. Switch one reverses the whole pickups phase relation to the neck, which means you won’t hear a difference unless the 3 way pickup switch is in the middle position. Switch two is the coil tap for the bridge. Neck switch one reverses phase of one coil only. The second neck switch taps that coil.

I suppose I should throw some subtle errors in there so when you try this yourself using just my diagram you’ll screw it up and have to bring it to me but I’m too busy to fix your mistakes. (Nothing worse that trying to salvage burned up switches). Here’s the final product. Lots of tiny connections in a tight space. Basically I’ve just taken a thousand plus words to explain you don’t need an engineer to plot out complicated guitar circuits, just a tech with a functional understanding of basic switch operation.


Super sick strat series pickup wire options 

I recently had a customer slip into the Gutter with his American Strat (I greese the sidewalk to “attract” customers). At some point he had a push pull pot installed giving him three series modes. You can see the mod detailed here.

While in series mode these are the pickup switch combinations.


  1. Bridge and neck in series
  2. Neck and mid in series and neck and bridge in series as parallel pair
  3. Neck and mid in series
  4. Neck
  5. Neck

As you can see position 4 is boring and redundant. The customer is an adventerous go getter and wanted another option for that switch position. The circuit doesn’t lend itself easily to other options.

Fortunately the customer, we’ll call him Cus for short, also wants a master treble and a master bass cut. This frees up one half of the 5 way pickup selector…. Interesting. Thinking, head scratching. I could just google a solution but I prefer a novel approach.

Let’s look at that middle bastard and figure out why he’s too subborn to TURN THE FUCK ON when pup switch is at 4. So a litle about electricity. Like water (and myself at times) it has little will of its own so will follow the path of least resistance. Pickup coils are essentially just a long, winding, miserable, grueling path of resistance. When a pickup circuit is connected correctly from ground through the coil to positive the electrons have no choice but to rejoice when the strings excite the magnet mist. (Stay with me). Looking at the PP switch (it’s a technical term, look it up) we see that the middle negative can either be connected to the ground lead or the wire going to the 5th lug of the pickup switch which also happens to be connected to the positive lead of the neck pickup. Same with the bridge but we don’t care about that right now. When PP switch is down electricy can flow from ground through neck coil to postive out to the negative entry of the middle,through its coil and to the 4th switch lug creating the series connection. But you can see all that. (Nevermind that pickups induce an AC current, it’s just eaiser to think about it this way).

So now that we are all electrical engineers we can clearly see what the problem is. No? Since water, er, electricity is kinda lazy it doesn’t want to go through the middle even when it has a path because while in the 4th position there are two paths and one is much easier than the other, through the neck and out the jack.

Cutting to the chase since Cus needs his guitar back I decided to use the now free half of the pickup switch to change the middle pickups ground path while in the 4th. But there is a snag. For reasons I’m too tired to explain the 3rd and 2nd terminals cannot be connected on this half of the switch to work correctly. My hack solution was to cut the wiper in the switch that connects them. Only it’s a fender switch and they are a pain to disassmble. So I used an asian enclosed five way and opened it up. See below, go ahead, you can look, it’s asleep and won’t mind a peak at its insides.

cut wiper

Long story short I wired it up so the neck and mid are in parallel in the 4th position. Cus already has that option when the series switch is disengaged and the strat functions as usual but fuck it, he’s happy with it.
