WHAT IS THE DIFFERENCE BETWEEN SERIES, PARALLEL & SPLIT?
The sonic differences between series, parallel and split sounds also vary between vertically stacked pickups (single coil size) and side by side pickups (traditional humbucker).
On a stacked pickup, series and parallel are both hum-free sounds with series being the louder and fuller of the two. The series sound replicates the sound of a single coil but without the hum. The split sound is a true single coil with all the wonderful tones we expect and the hum that goes with them. This sound is also the loudest of the three sounds. This is because the two coils of the pickup are not hearing the string equally due to their stacked configuration. Parallel is a cleaner, lower-output, hum-canceling single coil tone.
With a side by side humbucking pickup both coils are hearing the string equally. The series sound is the traditional strong, mid-focused humbucker tone. It is louder than both the split and parallel sounds. The split is a true single coil and the parallel produces a weaker humbucker tone.

Overwound pickups sound shitty to me. Increasing the windings seems to increase the midrange spike and decrease the top/bottom, and they end up sounding harsh and muddy. You lose the sweetness and clarity of the original design.
berlinbetty wrote: Also, in my research today, I discovered one thing you can do is add windings to a pickup and that got me to thinking about continuing the CIJ pups from where they stop to winding more wire all the way to the edge of the bobbin. I wonder what that would sound like with those deep windings being wider...
People get the idea in their heads that "more = better" but that's definitely not true in guitar pickup design. Increasing the windings makes a pickup louder but at the expense of sounding less pleasant. "Less = better" is also not such a great idea - a weak sounding pickup is no use to anyone.
When these things were actually being invented, Leo Fender and Seth Lover and so on experimented with the amount of windings they put on their designs, and the reason they ended up choosing the amounts they chose is because that's what sounded good. There's some wiggle room there, but if you get too far away from the original specs, you start sounding bad.
Have you ever heard one of those incredibly high output shredbuckers? Loud, yes. But incredibly harsh and muddy.
Electric guitar pickup
A humbucking pickup, humbucker, or double coil, is a type of guitar pickup that uses two wire coils to cancel out the noisy interference picked up by coil pickups. In addition to electric guitar pickups, humbucking coils are sometimes used in dynamic microphones to cancel electromagnetic hum.
The "humbucking coil" was invented in 1934 by Electro-Voice, an American professional audio company based in South Bend, Indiana that Al Kahn and Lou Burroughs incorporated in 1930 for the purpose of manufacturing portable public address equipment, including microphones and loudspeakers.
The twin coiled guitar pickup invented by Arnold Lesti in 1935 is arranged as a humbucker, and the patent USRE20070 describes the noise cancelation and current summation principles of such a design. This "Electric Translating Device" employed the solenoid windings of the pickup to magnetize the steel strings by means of switching on a short D.C. charge before switching over to amplification.
In 1938, A.F. Knoblaugh invented a pickup for stringed instruments involving two stacked coils U.S. Patent 2,119,584. This pickup was to be used in pianos, since he was working for Baldwin Piano at the time.
The 1939 April copy of Radio Craft Magazine shows how to construct a guitar pickup made with two identical coils wrapped around self-magnetized iron cores, where one is then flipped over to create a reverse-wound, reverse-polarity, humbucking orientation. The iron cores of these pickups were magnetized to have their north-south poles at the opposite ends of the core, rather than the now more common top-bottom orientation.
To overcome the hum problem for guitars, a humbucking pickup was invented by Seth Lover of Gibson under instruction of then-president Ted McCarty. About the same time, Ray Butts developed a similar pickup that was taken up by Gretsch guitars. Although Gibson's patent was filed almost two years before Gretsch's, Gibson's patent was issued four weeks after Gretsch's. Both patents describe a reverse-wound and reverse-polarity pair of coils.
A successful early humbucking pickup was the type which is nowadays known as the "PAF" (literally "Patent Applied For") invented by Seth Lover in 1955. Because of this, and because of its use on the Gibson Les Paul guitar, popularization of the humbucker is strongly associated with Gibson, although humbuckers had been used in many different guitar designs by many different manufacturers before. Rickenbacker offered dual coil pickups arranged in a humbucking pattern beginning in late 1953 but dropped the design in 1954 due to the perceived distorted sound, which had stronger mid-range presence.
The Gibson Les Paul was the first guitar to use humbuckers in substantial production. Over the following decades, variants of practically every important type of electric guitar have also been factory-equipped with humbuckers, even the types which are traditionally most associated with single-coil pickups, like Fender Stratocasters and Telecasters. In particular, the replacement of the bridge pickup in a Stratocaster-type guitar with a humbucker, resulting in a pickup configuration noted as H-S-S (starting at bridge pickup: H for humbucker, S for single coil) has gained much popularity. Guitars in this configuration are sometimes referred to as "Fat Strats", because of the "fatter", "rounder" tone offered by the humbucking pickup, and are also closely related to the development of the "Superstrat" style of guitar.
In any magnetic pickup, a vibrating guitar string, magnetized by a fixed magnet within the pickup, induces an alternating voltage across its coil. However, wire coils also make excellent antennae and are therefore sensitive to electromagnetic interference caused by alternating magnetic fields from mains wiring (mains hum) and electrical appliances like transformers, motors, and computer screens, especially older CRT monitors. Guitar pickups reproduce this noise, which can be quite audible, sounding like a constant hum or buzz. This is most noticeable when using distortion, fuzz, compressors, or other effects which reduce the signal-to-noise ratio and therefore amplify the unwanted interference relative to the signal from the strings.
Humbuckers work by pairing a coil that has the north poles of its magnets oriented "up" (toward the strings) with another coil alongside it with the south pole of its magnets oriented up. By connecting the coils together out of phase, the interference is significantly reduced via phase cancellation: the string signals from both coils add up instead of canceling, because the magnets are placed in opposite polarity. This dramatically improves the signal-to-noise ratio. The technique has something in common with what electrical engineers call "common-mode rejection", and is also found in the balanced lines used in audio equipment. By convention, humbucker coils are both wound counterclockwise. The coils can be connected in series or in parallel in order to achieve this hum-cancellation effect, but humbucker pickups tend to be connected in series because that doubles the signal of the strings while keeping the hum reduced.
Many solid-body guitars feature cavities only for single-coil pickups. Installing full-sized humbuckers in this type of guitar requires additional routing of the woodwork, and/or cutting of the pickguard if the instrument has one. If the process is not carefully done, the instrument's body and pickguard may be damaged. For many guitarists, this is unacceptable, especially for expensive vintage guitars where it is vital to preserve cosmetic appearance. As a result, many pickup manufacturers now produce humbucking pickups compacted into the size of a single coil. Many different kinds of mini-humbuckers are available from numerous manufacturers, and they produce a wide range of different tones. The most common design is very similar to a traditional humbucker.
As a concept similar to mini-humbuckers, a stacked pickup offers the more subtle and delicate sound of a single-coil, while still retaining the hum-cancellation properties of a humbucker. One of the coils simply has no magnets, so the inverted signal of this coil only serves to cancel out the hum picked up by the other coil, with the actual string signal remaining unaffected. This is often used on bass guitars, where the type of pickups used has a more substantial effect on the instrument's overall sound, and the lower range of note fundamental frequencies can match frequencies typically more heavily affected by hum. This is often called a "stacked" pickup, because the coils are most often "stacked" vertically, with the coil containing magnets placed closer to the strings.
Another design known as the rail humbucker features a single magnetic component spanning across the entire string width of the instrument. These pickups look like a normal mini-humbucker, except without the typical dots corresponding to the magnetic pole-pieces. This is sometimes expanded into a normal-size "quadrail", or double humbucker, effectively combining 4 coils connected in series to produce an extremely high-output pickup. The Kent Armstrong "Motherbucker" is an example of such an overpowered pickup.
The same type of rails can also be found in a normal-size humbucker, however. Heavy metal guitarist Dimebag Darrell made heavy use of this type of pickup wired in the bridge position. These tend to also sound fuller and have a higher output and bass response than the single coil-size version. DiMarzio has designed and sold many such pickups.
Coil splits and coil taps
Some guitars which have humbucking pickups feature "coil splits", which allow the pickups to act as "pseudo-single" coils by either short-circuiting or bypassing one coil. The electrical circuit of the pickup is reduced to that of a true single coil so there is no hum canceling effect. Usually, this feature is activated using a miniature toggle switch or a DPDT push-pull switch mounted on a potentiometer. Some guitars (e.g., the Peavey T-60 and the Fender Classic Player Jaguar HH) make use of a variable coil split circuit that allows the guitarist to dial a variable amount of signal from the second coil, from pure single-coil to full humbucker and everything in-between.
Another similar option is a series/parallel switch, which in one position causes the coils to be connected in parallel rather than in series. This retains the humbucker's noise-cancellation properties, and gives a sound closer to that of two single-coil pickups used together.
Coil splits are often wrongly referred to as a "coil tap". Coil taps are most commonly found on single coil pickups, and involve an extra hook-up wire being included during the manufacture of the pickup so the guitarist can choose to have all the windings of the pickup included in the circuit, for a fatter, higher output sound with more midrange; or switch the output to "Tap" into the windings at a point that is less than the full coil for a brighter, lower output, cleaner sound. For example: a full pickup coil may be 10,000 turns of wire and the "Tap" may be at 8000 turns. Because of the confusion between coil splits and coil taps—and the rareness of coil taps in general—it is difficult to find tappable single coil pickups for sale. However, pickup manufacturer Seymour Duncan offers tapped versions of many of their Telecaster and Stratocaster pickups.
Notable humbucker designs
- Gibson "PAF" - Seth Lover's humbucker design
- Gretsch Filter'Tron Prototype – Ray Butts' first humbucker design
- Fender Wide Range – Fender's first humbucker design, also by Seth Lover
- Epiphone (and later Gibson) mini-humbucker – a smaller humbucker design with adjustable pole pieces. A Gibson design which reduced their standard humbucker to fit in Epiphones routed for the 1950s Epi "New York" pickup, they were later used most famously in the Gibson Les Paul Deluxe.
- Gibson Firebird pickup – inspired by the Epiphone pickup, and shares its basic dimensions, but is different in terms of design, appearance, and tone, using single blade pole pieces.
- Q-tuner – neodymium magnet humbuckers
- EMG Pickups – active pickups since 1976
- Seymour Duncan - by Seymour W. Duncan
Other noise-reducing pickup designs
While the original humbucker remains the most common noise-reducing pickup design, inventors have tried many other approaches to reducing noise in guitar pickups.
Combining two single-coil pickups
Many instruments combine separate single coil pickups in a hum reducing configuration by reversing the electrical phase of one of the pickups. This arrangement is similar to that of a humbucking pickup and effectively reduces noise. Examples of this include the Fender Jazz Bass, introduced in 1960, which has used a pair of single coil pickups, one near the bridge and another one about halfway between the bridge and the neck—and many Stratocaster style guitars, which often have 3 pickups with the middle one reversed electrically and magnetically. The (usually) five-way selector switch provides two humbucking settings, using the reversed middle pickup in parallel with either the bridge or neck pickup.
If the pickups are wired in series instead of parallel, the resulting sound is close to that of a normal humbucker. It is even closer to a humbucker-type sound if you put the coils closer together.
In 1957, Fender introduced a split pickup to its Precision Bass, where one coil is serving the E and A strings, and the other one the D and G strings. This configuration is often referred to as a "split coil" pickup, which should not be confused with the possibility of "coil-splitting" a regular humbucker as discussed above. Both coils see nearly identical extraneous electromagnetic disturbances, and since they are wired in humbucking fashion, can effectively cancel them. However the majority of the sound signal of any single note will mostly be generated just by one of the coils, so that output level and tonal qualities are much closer to a regular single-coil pickup. The resulting "P-Style" pickup is usually regarded as the main ingredient of the "P-Bass" sound, and many variants of the design are being offered by many manufacturers. The concept was later developed into G&L's "Z-coil" pickup, which is used for standard guitars such as their Comanche model.
In 1985, Lace Music Products introduced the Lace Sensor pickup, which uses proprietary screened bobbins to reduce hum while preserving single-coil tone.
In the early 1980s DiMarzio introduced replacement pickups for Stratocaster and Telecaster guitars. These were of the stacked humbucker design, where the lower pickup coil functions solely to cancel hum.
The DiMarzio "Super Distortion" pickup, introduced in 1972, was the first after-market replacement guitar pickup. With its much increased output compared to the humbuckers that came installed in guitars of the time, it became an instant favourite of many hard-rock guitarists, and it remains a popular choice for a pickup upgrade decades later. The "Super Distortion" is noteworthy for its trademarked looks: two uncovered cream coloured bobbins. Other manufacturers were since limited to selling pickups with two black bobbins, or in the "zebra" look: with one bobbin black and one bobbin cream. (Of course they were still free to use wilder colours, but only in rare cases is such a choice regarded as befitting the look of any serious professional instrument.)

Stacks VS Single-Coil Sized Rail Humbuckers
A lot of solid-body guitars have pickup cavities that can only fit single-coils. This means that installing humbuckers on them would require some serious surgery on both the pickguard (if it has one) and the body itself. Sure, it can be done, but if you're not experienced or careful, you can easily ruin your guitar. Or you might have a vintage model and don't want to drastically change its appearance. This is where single coil stacks and rail humbuckers come in, pickups designed to give the hum-cancelling abilities of dual-coiled pickups without the size requirements. Below, we take a look at both of pickup designs and see exactly how they work.
Single Coil Stacks
As the name entails, single-coil stacks comprise of two single-coils stacked on top of each other, compacted to fit into the size of a regular single-coil. Because they look like a normal single-coil, they are often marketed as "noiseless" single-coil pickups, retaining the tone of a traditional single-coil while having the hum canceling ability of a humbucker.
When it comes to stacks, many argue that since they are humbuckers by nature, they lack the signature brightness and tone that true single-coils are known for. And while there are definitely stacked pickups that proudly convey their humbucker innards through their warmer, higher output tone, there are several stacked designs made to retain the traditional single coil tone with the hum canceling nature of humbuckers. In fact, many of these designs are so close that by the time you add every other piece of the signal chain into the equation, they are hard to tell apart from true single-coils.
Take Seymour Duncan, who have a selection of stacked pickups based on many of their popular single-coil models. For example, the STK-S6B Classic Stack is directly based on the SSL-5 single coil, which was originally developed as a bridge pickup for David Gilmour. With that in mind, check out the video below to hear for yourself just how well the STK-S6B Stacks comes to recreating the well-known single coil tone of the SSL-5:
STK-S6B Custom Stack Plus @ $85.00. A noiseless version of the popular SSL-5 Custom Staggered for Strat pickup, the Custom Stack Plus will give you all of the extra output and drive without losing that unique Stratocaster voice. The low notes are tight and snappy but the high end is focused without being overly bright, and the midrange has a slight vocal quality that adds an extra layer of expression to your sound. And it's dead quiet. This pickup is designed to look like a traditional Strat single coil, and it works great in the neck, middle, or bridge positions, or you can pair it with the Classic Stack Plus Strat in the neck and middle positions.

Moving on to the next design, we have rail humbuckers. While stacked pickups are able to fit two pickups into the size of a single coil by placing them on top of each other, rail pickups do the same by making each half as thick, leaving them side by side like you would with a regular humbucker. In order to make them thinner, rail pickups comprise of two thin pole pieces that resemble a rail. And unlike single-coils stacks, which are usually made to retain a single-coil tone, rail humbuckers are made to sound like true humbuckers
Single-coil sized rail humbuckers are often used in conjunction with stacked pickups in order to create a very high output pickup. In these designs, you are essentially fitting in four single coil pickups into the size of a single humbucker.
The rail design isn't just used on single-coil sized pickups either and can be found on normal sized humbuckers too. For example, the late Dimebag Darrell was well known for using regular sized rail humbuckers in the bridge position. As far as tone goes, they tend to sound thicker, with a higher output and attack than single-coil sized rail humbuckers.
SHR-1 Hot Rails @ $85.00. Seymour Duncan's Hot Rails pickup is one of the highest output pickups Duncan makes, and also one of the most popular. The Hot Rails uses a pair of blades coupled with a strong ceramic magnet and powerful coil windings to create a pickup that's full and fat with a ton of sustain - perfect for classic rock, but also lending itself very well to more aggressive tones such as garage rock or metal. Best of all, these humbuckers - and all their beefy tone - fits inside a single-coil-sized pickup. Add girth to your tone with the Hot Rails!

Your Turn to Sound Off!
What type of pickup do you prefer?
Let us know in the comment section below!
When noiseless single-coil pickups are discussed, it won’t be long before someone says that they can never sound exactly like a real single coil. The fact that they’re humbuckers at the core means that some of that high-end sparkle disappears. There are some things to remember at this point.
Firstly – which real single coil are they talking about? They all sound different already. Are we meant to assume that there’s some unifying characteristic between every single coil pickup, missing from none of them, but missing from all noiseless versions? Seems unlikely.
Secondly, these are small differences we’re talking about here. Yes, when you are playing clean, alone, you might hear some differences. Not necessarily negative differences, but differences. But in a band situation, volume up, gain rolled up a bit, these differences all but vanish. What you’re left with is single coil tone, without the hum creeping in on all the quiet bits.
Thirdly, a lot of these opinions were formed ten to fifteen years ago when noiseless single coils started to take off a little more. But in that time, the technology has come on in leaps and bounds. It’s really quite difficult to find a noiseless single coil now with the problem of lost treble.
On top of all this, I have bad wiring in my house. I love single coil sounds, but the hum is really unbearable. So noiseless single coils are an absolute godsend for me.
I’m a big fan of the Seymour Duncan Stack Plus pickups. You can pretty much replace an SSL-1 true single coil with an STK-S4 Classic Stack plus, and the same goes for the SSL-5 or SSL-6 Custom pickups and the STK-S6 Custom Stack Plus. I have a Strat with two Classic Stack Plus in the neck and middle and a Custom Stack Plus in the bridge position. Having a hotter bridge pickup like that is a popular modification to a Strat.
Given that the STK-S6 is based on the SSL-5, and the SSL-5 was originally developed as a bridge pickup for David Gilmour, it seems appropriate that I should cover one of his solos to demonstrate the STK-S6 pickup:
But I wanted to also try a more vintage-type setup, with a lower output bridge.
Originally I put three Classic Stack Plus pickups in the guitar, but actually, this was a step too far. There just wasn’t enough output in the bridge position to keep up with the other two pickups, and the amount of treble produced by the vintage windings was too ice-picky.
Luckily, the folks at Seymour Duncan have thought of this, and this is where the Vintage Hot Stack Plus comes in. It’s just a hair hotter than the Classic Stack plus, which makes it perfect for the bridge position. It’s a lot like having a calibrated set of single coils – the bridge pickup has just enough extra windings on it to bring it up to the level of the other two pickups, without shifting the frequency response enough to stop it sounding like a vintage pickup.
The Stack Plus pickups are splittable. The main use for this would be to achieve hum cancelling if they were combined with a non-stacked single coil, or one coil from a humbucker. The latter is common in HSS Strats. Splitting the Stack Plus pickups simply removes the hum-cancelling coil from the equation, leaving in its place a genuine single-coil pickup.
So now I can play vintage Strat sounds in my living room to my heart’s content. Here’s a demo I recorded. There’s a clean demo and then a demo with a bit more gain. Sorry about the strange volume glitch at 3:00 – I have no idea what happened!
The Stack Plus pickups recently became available in parchment and cream, as well as the usual black and white – so there’s an option for every color scheme. The same goes for the single-coil-sized humbuckers and the rails pickups.

Stacked Single-Coil Pickups Good?
I'm getting hum a problem with my strat. Has anyone tried stacked humbuckers & are they as bright as normal single coil & do they stop hum ?
I'm getting hum a problem with my strat. Has anyone tried stacked humbuckers & are they as bright as normal single coil & do they stop hum ?
Hmm, a matter of preferences. They stop hum but OTOH they don't sound as bright and open as SC's
They are HBs. It's just the shape that changes, for those who own say a Strato.
It depends on the brand. There are many noiseless SC pups available. I use Dimarzio Area pups and I challenge anyone to identify them as noiseless by listening in a musical context....other than the lack of hum. There are differences but I've heard as much difference between various true SC pups as well.
If you use high gain tones, then the him can be intolerable in certain environments. Noiseless pups solve this 100%. If you use shimmering clean and glassy fender tones, it won't matter as much and YOU will hear the most difference. Your audience won't know apart from the dead silence.
Humbuckers can be wired as parallel or serial configuration. Either way stops hum, but serial is the classic humbucker sound, while parallel sounds much more like single coils. I would imagine stacked singles would either give you 4 wires, so you can choose, or they are pre-wired in one of the two configurations, depending on if they are marketed as providing single-coil or humbucker tone, but that's going to be semantics.
Have you shielded all your guitar cavities with copper tape ? It can do miracles.
I have a Seymour Duncan hot rails in my lone star strat. It's just like a humbucker. I can flick a switch and it sounds like a single.
So the general view is they aren't as clear & bright as SC's. Thanks for your replies. I guess to have a centre tap one where one can go SC of one chooses would be good. But even then still might not sound the same as normal SC because when centre tapped the working half of it wouldn't be like a full coil SC one?
It won't sound exactly like a single coil, but then again, it won't be drastically different. The idea behind those stacked single coils is to eliminate hum. I would go ahead and do it. But before you do, try out that suggestion of lining your electronics cavity with copper foil. Might eliminate your problem and you'll not have to spend on an upgrade. Merry Christmas!
I had Fender SCN's and DiMarzio Areas ('58 & '67) for years. They're both pretty good, but i liked Areas more. IMHO Areas are closer to a decent single coil, 'though they can be little too treble-heavy for some. All that said, nowadays i use Lollar Blondes in my HSS Strat (w/ Haussel VIN+ in bridge), and they are really good. They are also fairly silent for real SC's.
If money is not an option, i would probably opt for Ilitch Noise Cancelling System.
Merry Christmas to all.
Thanks for the tips. I've just emailed Ilitch ref their Noise Cancelling System to see what I need from them. They do a pick guard & a backplate with coils in that they say don't affect the sound & that cancels hum. I might try them 1st.
