4-Way Switching For Your Tele
We get asked about 4-Way Switching a lot. It’s a simple mod that when added to your Telecaster, puts your pickups in Series, instead of Parallel. You can get a pretty beefy tone with both pickups on like this, and it adds a new dimension to your favorite guitar.
WHAT’S THE DIFFERENCE BETWEEN PARALLEL AND SERIES?
In a standard guitar, like a Strat or a Tele, your pickups are in Parallel. What this means is each pickup has its own path of output. For instance, the White (hot) leads connect to the switch, and the Black leads attach to Ground. Series wiring puts your pickup’s outputs into your other pickups. To illustrate, we’ve made an illustration:
Parallel Wiring gives the pickup the shortest possible distance to the Output Jack. Series wiring gives the signal a much greater distance to travel. The signal experiences more resistance, thus getting bigger and beefier as a result.
You might have noticed a volume drop when you switch between pickups in the middle positions. With Parallel wiring, the perceived sound decreases when combined with another pickup.
For instance, if you only selected your Bridge pickup, it’s output is 100%. When combined with another pickup, say, the Middle pickup, it’s output seems to drop by approximately 25%. The combination of the Bridge and Middle might result in a total combined output of, say, 50%.
Series wiring combines the pickup signals in a way where the volume is louder and thicker. When your pickups are wired in series, the combined signals would equate to 200%.
Note: the above percentages are only used for explanation, and are not accurate.
HOW TO WIRE 4 WAY SWITCHING:
With a 4 Way Switch, you get the following switching capabilities:
- The Bridge
- Bridge and Neck in Parallel
- Bridge and Neck in Series
- The Neck
To wire it up, take a look at the following diagram:
Note: If your Neck Pickup has a cover, you will need to separate the jumper connecting the cover to ground and run a separate wire off of the cover to be grounded separately. For a How-To, check out our guide here.
How It Works:
Position 1: Bridge Only
Neck White = Connected To Output
Neck Black = Connected to Nothing*
*(Since this is the coil wire, the Neck pickup doesn’t have continuity)
Bridge White = Connected to Output
Bridge Black = Hard Ground to Pot
Position 2: Bridge & Neck Parallel:
Neck White = Connected To Output
Neck Black = Ground
Bridge White = Connected To Output
Bridge Black = Hard Ground To Pot
Position 3: Bridge & Neck Series:
Neck White = Connected To Output
Neck Black = Bridge White
Bridge White = Neck Black
Bridge Black = Hard Ground To Pot
Position 4: Neck Only
Neck White = Connected To Output
Neck Black = Ground
Bridge White = Connected To Nothing
Bridge Black = Hard Ground To Pot
If you know this is the mod you would like to do, you can order our pickups with a “3-Wire Neck“. What we will do is give you a lead that runs off of the cover. If you already have a Tele Neck and want to convert to a 4-Way Switch, you will need to solder a wire to your cover and remove the ground connection from your coil. Basically, clip the jumper wire that grounds your cover to your black lead. To see how this mod is performed, check out our guide here: Convert your Tele Neck into a 3-Wire Neck

Thanks, Tyler, for your clear wiring diagrams for a 4-way. It’s the 3rd or 4th try with a Peavey generation series 2 tele copy but I have a persistent problem. Everything works except this: no matter how I wire, going from neck pos. 4 to the series combo, pos. 3, it cuts out, dead. I’m not enough of an electrician to fix it, but can you offer an idea? Going from pos. 3 to 4 does not cut out.
Les,
Are you trying this with a new switch? It sounds a lot like a faulty switch or sweeper. If it’s working on position 3 when you move it to 4, it theoretically should work when you move it back.
Tyler
Tyler, it was a new Oak whatever 4-way and since I’ve wired it four times there could be some problems with the sweeper and loose solder. My friend the guitar builder tells me that the Peavey hum canceling pu at the neck, the defective position pu, has a split humbucker-like coil that may explain the red, black and shield wire from it. There is no pu cover so what’s the shield for? When I reversed red and black on the 4-way it was screwed up but differently! Thanks, still frustrated.
Les,
You might be best served taking this guitar to a luthier with experience with wiring and electronics. The shield is the “chassis” ground, and will ground all the metal in your neck pickup. I’m not familiar with Peavey pickups or how their wired. My guess is that you need to find the Hot wire and the Coil Ground wire. If there are wires tied together from your humbucker, that might be the series connection and thus should stay connected.
Tyler
Thanks, Tyler, I found that using both black and shield from the Peavey “humbucker” Tele pickup on a pot ground gave me a satisfactory solution, not perfect. I’ll certainly consider Fralin equipment in the future. I lived in RIchmond in the 70’s and love going back to VA.
I’m a lefty, so here’s a stupid question, can i simply order a “pre-wired custom telecaster control plate” off your web site with a 4-way switch tele configuration? Any reason I’d have to tell you it’s for a lefty tele?
Also, it comes pre-soldered, correct? I’d just have to solder the jack wires and pickup wires onto it?
Hey Matt,
You would want to tell us that it’s for a Lefty Guitar. We’ll use Lefty Pots, and wire it up accordingly.
It does come pre-wired. We can wire the Output Jack up for you, if you’d like. All you would need to do is solder the pickup wires to where they needed to be.
Tyler
Thanks Tyler. A few additional questions:
What brand Pots do you use for lefty?
Does your lefty 4-way switch control panel have Treble Bleed mod to clarity when turning the volume down?
Just to make sure, since I’ve seen the switch settings can be different per vendor online, you wire the switch so that position 3 is the Bridge/Neck in Series, and position 4 is the Neck by itself, correct? That’s what I prefer.
thx,
Matt
We use CTS Pots for left-handed pots.
That mod is called our “Volume Kit”, which we can install for you for an additional $5.
That’s how we wire our switches by default!
Thanks – Tyler
I’m trying this for a 2 humbucker setup. Neck is a braided Gibson, and bridge is a 4 conductor Dimarzio. I wired the Dimarzios black and white leads together ie in series. The switching is not working for me. The neck pickup stays on in all positions and the bridge pickup is not coming on in position 3.
Any help would be a God send.
John,
Double check your DiMarzio color codes, and also make sure that your switch is an Oak Grisby 4-Way switch. Each manufacturer can be slightly different.

I’m trying to do this mod on my G&L. Which by the way does not have a ground on the neck pick up. It is working in position 4, 3, and 2. However, position 1 is the same as position 2 –
it is not just a bridge pick up. It seems to be neck and bridge in parallel – just like position 1. I’ve gone over it so many times that my eyes are crossing. Any ideas?
Hey Nate,
Do you know what type of switch it is? This wiring is for the Oak Grisgsby 4-Way Switch. Your switch may be laid our differently than ours. Take a look at our “How Blade Switches Work” post to understand them.
Every time we wire up a switch, we study it to make sure how it works.
Tyler
If anybody else has this issue, I figured out the problem. The slot on the control plate for the blade switch was not long enough for the blade switch to reach position 1. I had to file away at the slot for a while to get the switch to fit. I will note that both the control plate and 4-way switch were brand-new Fender parts. Fender makes parts that don’t fit each other. Sigh
Thanks for getting back to me so quickly and thanks for the great diagram. This layout makes much more sense than the standard 4-way switch layout.
I watched this video a few times before I did mine. Everything went smoothly. I love that fourth position. I gig regularly with my tele and only take it out of position four when I need to sound like Luther Perkins.
How do I wire the 4-way switch if I would also like to install a bridge pickup with three wires?
Darryl,
You should be able to find a diagram somewhere online for this. We only use 3-Wire Tele Necks.
Tyler
Great post, Tyler.
How do you make such terrific drawings? If you haven’t already, check out the rest of 4-way switch wiring diagrams on the internet. Your’s are way better. Well done.
Thanks Robert.
I use a couple of awesome programs and a lot of practice. Thanks for the love.
If the neck pup is from a strat is there an issue with not having a cover
Dave – thanks for your question. If you don’t have a common ground, (like a Tele Neck, which grounds all the metal), then you risk sending your ground signal through to your amp. What this could equate to is a popping sound or a zapping sound when you touch the pickup, especially the magnets.
So is there a way to do the 4 position wiring with a Strat Neck pu that does not have a metal cover?
I want to have the 4 way Tele switching on a mod I am doing with a Strat neck p/u and a bridge Humbucker… if possible.
Tom,
Sure thing. Just keep in mind that you might have a bit of ground noise enter your signal when you put the pickups in series, if you’re going that route.
Tyler
useful info, thanks so much!
in the series wiring does it matter which pickup is first in line.
Hey Jim! Nope!
Follow up. I know I could sit down and try to figure it out based on the schematic, but instead of snipping the wire in the neck pick up I did so on the bridge and then will ground the bridge plate (and strings) to a pot. Will this change anything in the wiring diagram above?
Tyler,
I haven’t had a chance to experiment with this yet. Let me know how it goes.
Tyler
I see the wires to the output labeled Hot and Ground. In this diagram is that true for the pickups as well or are we flipping the hot and ground on one of the pickups in order to have a reverse polarity?
