Here’s a workaround to get a similar configuration without having a third pickup. Plus, this serious tone weapon can be integrated into any given Telecaster wiring.
Hello and welcome back to Mod Garage. After writing the column about the Brent Mason Telecaster wiring in October 2021, I received a lot of requests from you about a more practical and non-invasive version of it. Well, you asked, and the Mod Garage delivers.
A lot of people don’t want to route an additional hole into their Telecasters to add a third pickup in the middle position, which is a massive task. I totally understand this, so let’s see what can be done instead, and let’s add some more tonal flexibility, which was another common request after that article.
The good news is a lot can be done. We touched on this multiple times in past columns: mimicking Stratocaster in-between tones with a Telecaster without having a middle pickup using half-out-of-phase wiring, for example. Some time ago we explored the Bill Lawrence way of doing this (“Mod Garage: The Bill Lawrence 5-Way Telecaster Circuit”) and the Jerry Donahue Telecaster wiring as well (“Decoding Jerry Donahue’s 5-Way Telecaster Wiring”). These two columns are great starting points to read about the basics of half-out-of-phase wiring and what it does.
In general, there’s nothing wrong with using these two wirings the way they are. But our goal is to get a little bit closer to the Brent Mason Telecaster wiring, plus add more tonal flexibility. Brent Mason’s wiring is straightforward—basically it’s a normal Telecaster wiring with an added middle pickup that has its own volume pot. Mason’s Telecaster is loaded with three humbucker pickups for trouble-free performance regarding hum and noise in both studio and live situations. But it doesn’t have any additional switching for splitting the individual humbuckers, so there are a lot more sounds under the hood to discover. If you need them or not ... well, it’s all up to you. The basic setup works well for Brent, and he can get his signature sounds in any given situation, but it’s not a crime to want more flexibility.
A lot of people don’t want to route an additional hole into their Telecasters to add a third pickup in the middle position, which is a massive task.
The basic plan for today looks like this:
1. Swap both pickups on your Telecaster for the correct Brent Mason models.
2. Add a triple-sound switch to each of the two pickups.
I will show you how to do this in a way you can integrate into any given Telecaster wiring, but to get the most out of it, I recommend combining it with the Jerry Donahue wiring. This way, you will receive an ultra-flexible Telecaster wiring that can also cover basic Stratocaster in-between tones.
Let’s start with the pickups. Brent uses Seymour Duncan pickups. If you want to get as close as possible you should use the following models:
- Bridge position: Vintage Stack Tele STK-T3b, which is a vintage-flavored, traditional-sounding humbucker with 4-conductor wiring.
- Neck position: Vintage Mini Humbucker, built-in 180 degrees flipped, so the open pole pieces are facing the bridge rather than the neck for more high-end and clarity in the tone. The pickup also sports a 4-conductor wiring.
If your Telecaster has the traditional vintage routing under the hood, the cavity for the neck pickup must be enlarged to make the mini humbucker fit, which can be a downside if you want to plug ’n’ play. If enlarging the routing is not an option for you, there are numerous humbuckers on the market that will fit into the routing, such as the Seymour Duncan Hot Rails and Vintage Stack Tele neck pickups. Almost every pickup manufacturer has such a pickup in its portfolio, so there are plenty of options.
Choosing a Stratocaster neck pickup will result in the same problem: They won’t fit into the standard vintage neck routing of a Telecaster.
Rig Rundown: Brent Mason [2021]
It’s impossible to overstate Brent Mason’s impact on country and, arguably, even rock guitar. Over the course of his more-than-35-year career, Mason has perf...If you have a full humbucker routing under the hood, which you can find on a lot of newer Telecaster models, you’re good to go the easy way, but keep in mind that you’ll have to enlarge the hole in the pickguard as well. Don’t forget to build it in 180 degrees flipped, like on Brent’s Telecaster, to get closer to his trademark sounds.
Changing the bridge pickup should be a no-brainer: It’s an easy 1:1 swap.
For adding the two triple-sound switches, you’ll need two DPDT on-on-on mini toggle switches. You can’t use push-pull or push-push pots for this because they’re only available as on-on or on-off versions, so the third switching position is absent. But on common Telecaster control plates, it’s no problem to place two of these switches between the two pots and you don’t need Reiki hands to operate them. But again, two holes must be drilled, so it’s not an easy mod if you want to make it look good on the control plate, straight in one line.
With the switches, each of the pickups will have three operation modes and tones:
- Full humbucker (both coils in series)
- Real single-coil split (one coil shut down to ground)
- Single-coil-esque tone (both coils in parallel)
This, combined with the second pickup plus all the features of the Jerry Donahue wiring, results in a lot of different tones. While the humbucker and single-coil-esque tones are free of hum and noise, the real single-coil split mode will also behave like a real single-coil, picking up all kinds of hum and noises.
This switching was made popular by the DiMarzio company under the name “dual sound,” which I think is confusing because it’s a triple-sound switch, not a dual one.
The good thing is that this switching is placed directly after the pickup, so in layman’s terms this means: The four wires from the humbucker are connected to the switch but only two wires are going out of the switch (hot + ground), so it’s super easy to add this feature to any given wiring.
You simply solder the hot output of the switch to the spot where usually the hot wire of the pickup is connected and solder the ground coming from the switch where the ground wire of the pickup is usually connected, and you’re done. So, it’s absolutely independent from the wiring that’s coming after the switch, and you can transfer it to any given guitar.
You can’t use push-pull or push-push pots for this because they’re only available as on-on or on-off versions, so the third switching position is absent.
Now, let’s focus on the bridge pickup to demonstrate the wiring on the switch, as seen in Fig. 1. Please note the jumper wire on the switch and don’t forget to solder it. The middle position of the switch is the real single-coil split. With the toggle up, it’s full humbucker, and the toggle down is the hum-free single-coil-esque tone. I used the Seymour Duncan color code for this because we’re talking about Seymour Duncan pickups. If you want to use pickups from a different company, you’ll have to transfer the color code using one of the many transfer charts online.
The wiring of the neck humbucker is exactly the same: the bare ground wire of both pickups always goes to ground. After wiring both pickups to their mini toggle switches, you only have to connect four wires before you’re done. The hot output of the neck pickup switch goes to the spot where usually the hot wire of the neck pickup is connected to and the hot output of the bridge pickup switch to where the hot wire of the bridge pickup is connected to. Likewise, the ground output of the neck pickup switch goes to the spot where usually the ground wire of the neck pickup is connected, and the ground output of the bridge pickup switch goes where the ground wire of the bridge pickup is usually connected.
Congratulations, you’re done! This is a good alternative to the original Brent Mason wiring, and it adds many more possible tones and variations. Especially in tandem with the Jerry Donahue wiring, this is a serious tone weapon with an almost unlimited number of sounds.
That’s it for now. Next month we’ll continue with another guitar mod, so stay tuned. Until then ... keep on modding!
Fender just released a signature model for one of Nashville's most prolific session guitarists. Let's look inside his number one guitar.
Welcome back to Mod Garage. Let's take a closer look at what's usually referred to as the Brent Mason Telecaster wiring. It's also been called "Telecaster blend wiring" or "Nashville Telecaster wiring," and I think it's time to cover this one in detail for several reasons. First and foremost, I've received numerous requests from you, dear readers, to do this. Fender recently released a faithful replica of Brent Mason's Telecaster, and also, my PG colleague John Bohlinger did a great Rig Rundown video with Mason just weeks ago. Mason is an outstanding player and absolutely nice guy so it's only logical to cover the wiring of his famous '67 Telecaster. Unless you're living in a cave, you've heard about Mason and his playing, which he's laid down on more Nashville studio records than one can count.
Mason's famous "automobile primer gray" 1967 Telecaster has three humbucker pickups and three controls. It's basically a standard 3-way Tele pickup-switching circuit plus an additional volume control to blend in the middle pickup. These are the pickups Mason uses in his Telecaster, all from the Seymour Duncan company:
Rig Rundown: Brent Mason [2021]
- Neck position: Vintage Mini Humbucker (Mason tenderly calls it a "Baby Humbucker"), built-in 180 degrees flipped, so the open pole pieces are facing the bridge rather than the neck for some more high-end and clarity in the tone. The pickup is wired with both coils in series for full humbucking functionality and no control to split it.
- Middle position: Mason is using an older version of the Hot Stack Strat STK-S2 with the red pickup cover and engraved Seymour Duncan logo on top. The current model has a white cover that's partly open on top. Hopefully, the iconic early red pickup cover will be available again for that special look. The pickup is wired with both coils in series for full humbucking functionality and no control to split it.
- Bridge position: Vintage Stack Tele STK-T3b, which is wired with both coils in series for full humbucking functionality and no control to split it.
These are the pickups installed in Brent's original Tele and also the pickups Fender is using for the signature model. This is an HHH pickup combination, by all means. Why Fender labelled it an SSH combination on the webpage ... well, we don't know.
In general, you can use any given pickup combination for this wiring. If you want to be as close as possible, this is your shopping list. If you only want to get in the same ballpark, you should use a vintage-flavored Tele bridge pickup, a hotter (overwound) Stratocaster middle pickup, and a PAF-style humbucker or hot P-90 for the neck position. No matter if they're single-coils or humbuckers, it will work.
"This wiring worked well for Mason right from the start: A hum-free operation is absolutely essential for work in a studio."
Why did Mason choose such an unusual pickup combination, you might ask? According to Mason himself, he didn't have much money in his early career and could only afford one guitar. This had to cover everything he needed in the studio. Brent wanted a Telecaster bridge pickup to cover all the country playing that was popular in the early '90s. For this, he also installed a B-Bender (Joe Glaser system, Mk1 version). He also wanted a Stratocaster tone, especially the in-between tone from bridge and middle together in parallel, and a Les Paul-ish tone from the neck position. So, the pickup combination he chose made sense, and Nashville's Joe Glaser did the wiring for him, which is the reason why Mason named this wiring "Glaser wiring."
This worked well for Mason right from the start: A hum-free operation is absolutely essential for work in a studio. But the wiring underwent some evolution during the years regarding the push-pull pot, which is the master tone control. This was initially wired to split the Hot Stack middle pickup into a single-coil, and all the diagrams of this wiring that are online right now still display this version. Today, the push-pull pot is wired to switch the middle pickup on and off. This is also the way Fender's Mason signature Tele is wired and what I'll be showing you. If you want the older wiring, you can find several examples online. They are also correct, but simply not up to date with Mason's current wiring.
I asked Mason directly about this, and I'm more than happy to share his reply:
"Basically, it's a standard 3-way switch with an extra volume knob that controls the middle pickup. Three knobs, left to right: volume (for neck and bridge), volume (middle), tone (for all 3) with an extra feature to pull on the tone knob to cut the middle pickup off or on. The middle pickup with the volume knob enables you to roll in the desired amount to blend with either neck or bridge. The pull knob on my original '67 Tele cuts the Seymour Duncan Vintage Stack split coil in half to single-coil. Later on, over the years I found that feature useless. We decided to make that tone control knob cut the middle pickup off and on. Upward position is off. The pickups are all Seymour Duncan; Mini Humbucker in front, Hot Stack in middle, and Vintage Stack in bridge." —Brent Mason

So, what do we need for this wiring? We know the pickups, but we don't know exactly what's used for the electronics and how it's wired. Fender didn't release a wiring diagram for the signature model yet and Joe Glaser didn't publish anything about it. My diagram (Fig. 1 - scroll below) will work exactly as it should, but maybe the original guitar is wired slightly different. As you know, many roads lead to Rome.
I was able to find a photo of the wiring Fender did (Photo 1) and extracted a still shot of Brent's original guitar from the Fender video mentioned above (Photo 2).

On these two photos, we can clearly see:
- The push-pull pot is wired to switch the middle pickup on and off.
- All three pickups are wired for full humbucking functionality with both coils in series.
- No treble-bleed networks are used on the two volume pots.
- Mason still has the '67 original Sprague "Circle D" 0.05 uF high-voltage ceramic tone cap in his guitar.
This only leaves us with two unknown parameters: resistance of the three pots, and on/off wiring of the middle pickup. I think it's three 250k audio pots, but if you want a tad more high-end, using a 500k audio push-pull master tone pot is worth a try. I would use two 250k audio volume pots to benefit from the much better taper range compared to a 500k pot—the nature of the (passive) beast.
To activate or cut off the middle pickup there are two different ways: connecting the pickup to the switch or using a push/pull volume pot for the middle pickup. I decided to use the second version because when connecting the pickup directly to the switch, the volume pot stays connected to the circuit, adding some load to it, resulting in less high-end. Please note that the master tone pot will not work on the middle pickup when the master volume is not set to "10" (aka fully opened). When you start to roll down the volume, the middle pickup gets disconnected from the master tone, no matter if you switch the pickup itself or the volume pot—that's part of the game.
Fig. 1
To keep the wiring diagram (Fig. 1) as clean as possible, I showed all ground connections only with the international symbol for it rather than drawing several black wires through the diagram. I also only show two pickup wires (hot and ground) but keep in mind that these are humbuckers with a four-conductor wiring plus separate ground wire, so you'll have to solder some wires together to end up with only two pickup wires. The separate ground wire always goes directly to ground (casing of a pot, etc.) and assuming you're using Seymour Duncan pickups, you'll have to follow this color code:
- Black wire = hot output
- White and red wire are twisted together, soldered, and isolated
- Green wire = ground
For other pickups, you'll have to use the corresponding color code from the manufacturer. For single-coil pickups, you don't need to do all this.
Is this wiring perfect or are there any mods that can be done? At least it's perfect for Mason and his playing. If it's good enough for him, it should be good enough for all of us. But this is only half the truth.
If you have Brent's playing chops, you don't depend much on any equipment. Even with the cheapest, meanest, off-tuned junk guitar, Mason will sound much better than most of us. The better you play, the less you depend on equipment. It's absolutely okay and no sacrilege to mod this circuit to your personal needs. If you want to use the push-pull pot for splitting one of the pickups rather than switching the middle pickup on and off ... go for it! If you want to use treble-bleed networks for the volume pots or want to implement splitting for all three pickups, there's no law against doing so.
That's it for now. Next month we'll continue with our DIY relic'ing project.
Until then ... keep on modding!He's played on more than a thousand albums. Now, here's a close-up look at this Nashville session legend's live rig.
It's impossible to overstate Brent Mason's impact on country and, arguably, even rock guitar. Over the course of his more-than-35-year career, Mason has perfected a tone that's inspired an untold number of players, and there's even a Tele mod that bears his name. He's also a highly respected and successful producer and solo artist, a member of the Musicians Hall of Fame, has won the Academy of Country Music's Guitarist of the Year award 12 times, and there's a Grammy on his mantle.
Mason's live gear—which he showed us before his recent gig at Nashville's 3rd & Lindsley—is simple and cool as hell, but it's not his guitars or amps that've made him a hero. It's his imagination, virtuosic chops, and pure musicality.

Honky Tonk Excalibur
Mason's battered and highly modified 1967 Telecaster has probably been on more hit country songs than any other guitar. The car-paint re-fin happened before he got it, but most of his mods were done by top Nashville luthier Joe Glaser. His pickups are a neck Seymour Duncan humbucker, a Duncan single-coil in the middle (for the famed Brent Mason pickup mod), and another Duncan single-coil in the bridge.
Top of the Whirl
The headstock on Mason's well-traveled Tele shows its years, and plenty of character accumulated over its storied history. His old paint features locking tuners and a Glaser B-bender.
Not Yer Average Tele
Here's a close-up of that extra pickup. Note the additional speed dial, too. The bridge and neck pickups are controlled by a standard 3-way switch, with a master volume and tone. The middle pickup has its own individual volume control that lets Mason feather in as much or little as he wants, to combine its output with one or both of the other pickups.
Meet the Mason Model
The only other guitar Brent brought to this gig was his new Fender Brent Mason Signature Telecaster. This alder-bodied Tele has basically the same ingredients of his original, but with a lot less wear and tear.
Bend It Like Brent
Here's a close-up of the arm of the Glaser B-bender. It has no screws, no slack, no wobble … but it does have a thumbscrew to fine-tune its destination pitch.
Perfect Strangers Side by Side
Here's the sensei and its student in a side-by-side comparison.
Four-Way Heat
Mason was switching between his 1964 Fender Twin Reverb and this early '70s Fender Super Reverb modded by Jeff Himes. The Super, with Mason's signal running into its no-frills Normal channel, did most of the heavy lifting on this gig.
Chairman of the Board
Mason's never been a big effects player, but his live pedalboard covers a lot of essential territory. It holds a Boss GE-7 Equalizer, a Wampler Ego Compressor, a Wampler Euphoria overdrive, an Xotic BB Preamp, Wampler's Hot Wired V2 distortion/overdrive, a Dunlop volume pedal with a Boss TU-2 Chromatic Tuner connected to its tuner out, a Fender Tre-Verb tremolo/reverb, a Fender Compugilist compressor/distortion, an Electro-Harmonix Memory Man 1100-TT, and a Live Wire ABY Box. It's all powered by a Truetone 1 Spot Pro CS12 with a Dunlop DC Brick for backup.
