A 4-wire humbucker ready for modding.
Hello and welcome back to Mod Garage. This month, we’ll talk about how to wire triple-shot humbucker pickups. I’ll explain what this means and how to do it, so let’s go.
When you have a humbucker with a traditional 2-conductor wiring, you don’t have any sound variation by itself—only together with another pickup that you can put in parallel or in series with it, in phase, out-of-phase, or half out-of-phase, and so on. With a 4-conductor wiring on your humbucker pickup, you have access to the start and the finish of each coil, and this can be used to get a total of four different tones out of it, whether it’s a bridge or a neck pickup. A 4-conductor wiring results in a total of five wires coming from such humbuckers:
- North coil start / north coil finish
- South coil start / south coil finish
- Ground = bare wire (goes always to ground)
The possible combinations and sounds you can dial in are:
1. Both coils together in series = standard humbucker operation mode.
This is the factory standard way all humbuckers are internally connected when they have a 2-conductor wiring with only hot and ground. This is also the standard way in almost every guitar loaded with one or more humbucker pickups, producing a warm, loud, and fat tone with maximum output and the humbucking function engaged.
2. Single-coil-esque humbucker wiring (both coils together in parallel).
This option gives you a single-coil-like tone but keeps the humbucking function engaged. You won’t get a crystal-clear Strat or Tele tone, but to me it sounds at least single-coil-esque, maybe closer to a P-90 than to a standard single-coil. It sounds different with any humbucker, so it’s a matter of trying it out.

3. Coil-splitting to the south coil.
This wiring is splitting the humbucker in half, shunting one coil to ground, leaving the other coil engaged like a true single-coil pickup. In this mode, the humbucking function is no longer active, so you’ll receive all kinds of hum and noise, just like with any single-coil pickup. Don’t expect a true Strat or Tele tone. If this is your goal, there are special humbuckers made of two real single-coil pickups. The downside of this special breed is they don’t sound very good as a full humbucker, so it’s always the art of compromising. Splitting to the south coil of the humbucker, which is the screw side, is recommended for neck humbuckers, but can also sound good for bridge humbuckers.
4. Coil-splitting to the north coil.
This wiring follows the same idea as #3, but will leave the north coil, which is the slug side, active. This version is recommended for a bridge humbucker because it gives a fuller sound compared to the screw side.
To clear up some terminology, there are several descriptions given to the individual coils of a humbucker and depending on the manufacturer of the pickup, they are sometimes used side by side: The (non-adjustable) slug coil is also called north coil or inside coil, while the (adjustable) screw coil is called south coil or outside coil.
Having two 4-conductor humbuckers in an HH guitar will result in four different sounds from each pickup. Plus, you can combine them for a total of 16 different sounds, which is a lot of choice, not counting possible additional options like phasing.
What sounds like a good plan or must-have often turns into a real issue, because space is your enemy! Try to do this on a Les Paul and you’ll face that there isn’t enough space for all the additional switches that are needed, and that’s the same with a lot of other guitars. So, some years ago Seymour Duncan came up with a clever product called the “Triple Shot.”
The good news is, you can get the exact same performance from a rotary switch, which costs only a fraction of a Triple Shot. The sad news is, you need one rotary switch for each pickup, and, naturally, you need space to place them somewhere on the guitar.
This is a humbucker mounting ring with two integrated slide switches and a ribbon cable going from the switches to a small printed circuit board (PCB), which is the connection terminal for the five wires coming from the humbucker plus a shielded output cable. The Triple Shot is available in different colors and shapes, so it’ll fit virtually any guitar, no matter if it has a flat (Strat, Tele, SG, etc.) or arched (Les Paul, 335, etc.) top. With the Triple Shot, you don’t have to drill any new holes into your guitar, and you don’t lose any controls by replacing them with switches or the like.
Operating the Triple Shot is easy, but it takes some getting used to. Because of the two slide switches, you need to know what combination will produce each sound, which can cause some confusion at the beginning. Another benefit is that the optical appearance of your guitar is not altered in any way and it’s easy to remove if you need or want to. An often-heard downside is the high price for the Triple Shot ($39 street). Personally, I think it’s worth the price because it’s high quality, but if you’re on a budget, this can be a deal-killer.
The good news is, you can get the exact same performance from a rotary switch, which costs only a fraction of a Triple Shot. The sad news is, you need one rotary switch for each pickup and, naturally, you need space to place them somewhere on the guitar.
For this you need a 2P4T rotary switch, which means it has two poles (comparable to the standard 5- and 3-way switches you all know) and four switching positions. Physically you have five lugs on each switching stage, with one of them being the output of this stage. The lugs are numbered from 1 to 4 and the output on a rotary switch is always labelled with a “C” for “common.” The rotary switch wiring you need is illustrated in Fig. 1.
Take care to get a good-quality switch. These switches are available in a wide range of quality and prices. There are open ones, like the one shown in the diagram, and closed ones. The trick is to connect both switching stages (output of stage #1 goes into stage #2), which is something you already know from your standard 5- or 3-way switch.
Fig. 2
Fig. 2 shows how to connect your 4-conductor humbucker to the rotary switch. With this wiring you receive the following switching matrix:
- Both coils in series (standard humbucker)
- Both coils in parallel (hum-free single-coil-like tone)
- Slug coil as single-coil
- Screw coil as single-coil
I chose the Seymour Duncan color chart for the diagram, but you can transfer it to any brand humbucker using color code transfer charts on the internet.
That’s it for now. Next month we’ll continue our relic’ing project, focusing on the neck and fretboard. We’re getting close to the finish line on that one, so stay tuned.
Until then ... keep on modding

Naturally, every recording Eddie Van Halen ever played on has been pored over by legions of guitar players of all styles. It might seem funny, then, to consider EVH solos that might require more attention. But your 100 Guitarists hosts have their picks of solos that they feel merit a little discussion. Some of these are deep cuts—get ready for some instrumental bonus tracks and Van Halen III mentions—and some are among the biggest radio hits of their time. Just because their hits, though, doesn’t mean we don’t have more to add to the conversation.
We can’t cover everything EVH—Jason has already tried while producing the Runnin’ With the Dweezil podcast. But we cover as much as we can in our longest episode yet. And in the second installment of our current listening segment, we’re talking about new-ish music from Oz Noy and Bill Orcutt.
Tinkering with theSDE-3 Dual Digital Delay suggested a similar, possibly enduring appeal. As an evolution of the Roland SDE-3000rack unit from the 1980s, it’s a texture machine, bubbling with subtle-to-odd triangle LFO modulations and enhanced dual-delay patterns that make tone mazes from dopey-simple melodies. And with the capacity to use it with two amps in stereo or in panning capacity, it can be much more dimensional. But while the SDE-3 will become indispensable to some for its most complex echo textures, its basic voice possesses warmth that lends personality in pedestrian applications too.
Tapping Into the Source
Some interest in the original SDE-3000 is in its association with Eddie Van Halen, who ran two of them in a wet-dry-wet configuration, using different delay rates and modulation to thicken and lend dimension to solos. But while EVH’s de facto endorsement prompted reissues of the effect as far back as the ’90s, part of the appeal was down to the 3000’s intrinsic elegance and simplicity.
In fact, the original rack unit’s features don’t differ much from what you would find on modern, inexpensive stompbox echoes. But the SDE-3000’s simplicity and reliable predictability made it conducive to fast workflow in the studio. Critically, it also avoided the lo-fi and sterility shortcomings that plagued some lesser rivals—an attribute designer Yoshi Ikegami chalks up to analog components elsewhere in the circuit and a fortuitous clock imprecision that lends organic essence to the repeats.
Evolved Echo Animal
Though the SDE-3 traces a line back to the SDE-3000 in sound and function, it is a very evolved riff on a theme. I don’t have an original SDE-3000 on hand for comparison, but it’s easy to hear how the SDE-3 bridges a gap between analog haze and more clinical, surgical digital sounds in the way that made the original famous. Thanks to the hi-cut control, the SDE-3’s voice can be shaped to enhance the angular aspect of the echoes, or blunt sharp edges. There’s also a lot of leeway to toy with varied EQ settings without sacrificing the ample definition in the repeats. That also means you can take advantage of the polyrhythmic effects that are arguably its greatest asset.
“There’s a lot of leeway to toy with varied EQ settings without sacrificing the ample definition in the repeats.”
The SDE-3’s offset control, which generates these polyrhythmic echoes, is its heart. The most practical and familiar echos, like quarter, eighth, and dotted-eighth patterns, are easy to access in the second half of the offset knobs range. In the first half of the knob’s throw, however, the offset delays often clang about at less-regular intervals, producing complex polyrhythms that are also cool multipliers of the modulation and EQ effects. For example, when emphasizing top end in repeats, using aggressive effects mixes and pitch-wobble modulation generates eerie ghost notes that swim through and around patterns, adding rhythmic interest and texture without derailing the drive behind a groove. Even at modest settings, these are great alternatives to more staid, regular subdivision patterns. Many of the coolest sounds tend toward the foggy reverb spectrum. Removing high end, piling on feedback, and adding the woozy, drunken drift from modulation creates fascinating backdrops for slow, sparse chord melodies. Faster modulations throb and swirl like old BBC Radiophonic Workshop sci-fi sound designs.
By themselves, the modulations have their own broad appeal. Chorus tones are rarely the archetypal Roland Jazz Chorus or CE type—tending to be a bit darker and mistier. But they do a nice job suggesting that texture without lapsing into caricature. There are also really cool rotary-speaker-like textures and vibrato sounds that offer alternatives to go-to industry standards.
The Verdict
The SDE-3’s many available sounds and textures would be appealing at $219—even without the stereo and panning connectivity options, a useful hold function, and expression pedal control that opens up additional options. The panning capabilities, in particular, sparked all kinds of thoughts about studio applications. Mastering the SDE-3 takes just a little study—certain polyrhythms can be dramatically reshaped by the interactivity of other controls and you need to take care to achieve identical results twice. But this is a pedal that, by virtue of its relative simplicity and richness and breadth of sounds, exceeds the utility of some similarly priced rivals, all while opening up possibilities well outside the simple echo realm

Guitar: The Green Snake
Reader T. Moody turned this Yamaha Pacifica body into a reptilian rocker.
I have always loved the reverse headstock, simply because nothing says 1987 (the best year in the history of the world) like a reverse headstock. The pickups are both Seymour Duncan—an SH-1N in the neck position and TB-4 in the bridge, both in a very cool lime green color. Right when these pickups got listed, the Buy It Now button once again lit up like the Fourth of July. I am a loyal disciple of Sperzel locking tuners and think Bob Sperzel was a pure genius, so I knew those were going on this project even before I started on it. I also knew that I wanted a Vega-Trem; those units are absolutely amazing.
When the body arrived, I thought it would be cool to do some kind of burst around the yellow so I went with a neon green. It turned out better than I imagined. Next up was the shaping and cutting of the pickguard. I had this crocodile-type, faux-leather material that I glued on the pickguard and then shaped to my liking. I wanted just a single volume control and no tone knob, because, like King Edward (Van Halen) once said, “Your volume is your tone.”

I then shaped and glued the faux-leather material in the cavity. The tuning knobs, volume knob, pickguard, screws, and selector switch were also painted in the lemon-lime paint scheme. I put everything together, installed the pickups, strung it up, set it up, plugged it in, and I was blown away. I think this is the best-playing and -sounding guitar I have ever tried.
The only thing missing was the center piece and strap. The latter was easy because DiMarzio makes their ClipLock in neon green. The center piece was more difficult because originally, I was thinking that some kind of gator-style decoration would be cool. In the end, I went with a green snake, because crocodiles ain’t too flexible—and they’re way too big to fit in a pickup cavity!
The Green Snake’s back is just as striking as the front.
