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

Hi
I love how clear the diagram is and the explanation you’ve added. So this is a dumb question, but i’m still trying to get my head around guitar wiring! It looks from the diagram above that the switch position to activate the bridge pickup is in the position corresponding to where the neck position should be (i.e furthest from the control knobs) and the position to activate the neck pick up is closest to the control knobs. I’m probably misreading the diagram but i just want to double-check before embarking on a wiring project! Thanks!
I definitely converted it to a 3 wire. Grounded the cover. I have done this with 3 different teles and grounded all the covers. And the neck pickups have no ground hum with the 4 way switch. But somehow the bridge pickup always does. It has confused me for a couple years now. I just gave up and always put the 3 way switch back in and just left the ground wire for the neck pickup cover grounded to the back of the volume like the rest of the grounds. I had to do this for one of my neck pickups anyways because the neck and bridge were out of phase so I had to reverse the hot and ground to get them in phase which meant grounding the cover separate. No hum with the 3 way switches. Odd… I have to be dong something wrong if it works for everyone else. Didn’t know if there were any obvious things to check beyond the ground for the cover of the neck pickup. I have all the body cavities shielded and they are all pretty quiet teles which is why it was so startling to have the ground hum show up with the 4 way switch. I have 2 of the switches since i assumed the first was defective. Same result…
I have tried to use this 4 way switch so many times and every time end up with a serious ground issue. The ground buzz any time my bridge pickup is on is terrible. Touching any metal makes it go away. Tried the switch on several teles and several wirings. Is this just part of the switch where this will always exist?
Hey Michael,
It sounds like you did not properly remove the ground connection from your Telecaster Neck Pickup? Convert Your Tele Neck Into a 3-Wire Neck Can you take a look into that?
Hi Tyler, If i don’t use a cover on the neck pickup. Do i still need to cut the ground on the neck pickup? TY and be safe, Joe
Hey Joe,
No – but, it helps to have Taped Magnets. This separates the coil wire from the magnets and prevents “hot” magnets.
The Oak Grigsby 4-way is worth the $$. My bcustom 44 MagnuM has bcustom’s SLC (simpleLogic controls:) two Oak Grigsby 4-ways, a 3-way toggle selector and a concentric pot. The dual humbuckers perform as 4 individual coils, selectable in any combination. You have either coil, series or parallel for both neck and bridge independently and can turn off one set of coils with a 3-way toggle. The pot lets you mix the amount of “other” pickup you want, so it doubles as a “capless” tone control. This beast is a Strat, Tele, and Les Paul all in one guitar.
Thanks heaps for the diagram – the order for the switching was just what I was looking for. 1 quick question. Usually most of the other diagrams have either the capacitor coming from the tone pot connecting to a ground point on the volume pot or if running to the case of the tone pot then having an additional wire from the tone pot to ground on the volume pot. Why do neither happen here? Is the body of the tone pot expected to ground via the control cover? Thanks.
Hello,
Got me thinking. What would adding a resistor as big as the pot, instead of the jumper wire in position 3 do? Would this resistance add to the pot, giving some highs back to a more muddy series mode?
Just read the article about tapping the pots and that used a resistor parallel to the pot, wondering if there’s a way to add to a pot by connecting a resistor in series.
Or maybe the series mode doesn’t get muddy at all?
Great articles people, sparked my curiosity!
Hello! I already have this setup with tele pickups and I assumed the same would work with some p90’s I got in another tele build. The P90’s have three wires (1+, 1 -, 1 ground) and when i wire them, in position 1 and 2 both neck and bridge can be heard and position 3 and 4 sounds like just neck. According to something I read higher up mentioned p90’s are only going to work if they are two wires? can any one comment why that is? Thanks!
Is there a reason the tone capacitor is wired on lug one of the tone pot and not lug two? All other diagrams I’ve seen with this modified 4 way wiring have that cap on lug two.
Great guide! I have a question I hope you could answer. I bought a used SSS Tele (neck and middle Dearmond Goldfoils, bridge stock) with a 5-way switch. The middle + bridge position were out of phase so I reversed the bridge’s pickup lead, including cutting the base jumper wire. Now I am thinking about taking out the Goldfoils for the stock neck pup and a 4-way switch. Will I have to anything different because of what I did with the bridge pup?
