Hello everyone! I'm planning to build a guitar. Every electric guitar should have pickups to sound. In my build I'd like to have HSS configuration: a humbucker in bridge and two singles. I will go with custom-made pickups, and therefore different options are possible. In general, I'm not sure about the question: should neck and middle single pickups be in reverse wound and reverse polarity? Not sure what are the pros and cons there, but I'm planning to use different switching options including series / parallel and, probably, phase switching as well. Thank you for your ideas.

Fender didn't start using RWRP middle pickups until the early 1970's, so there are those "vintage Strat" types who argue that none of the pickups should be RWRP for the true "vintage tone". Of course, since the point of a RWRP pickup is to reduce noise, when in combination with a non-RWRP pickup, the vintage set-up will be noisier than with a RWRP.
Typically, on regular SSS Strats, the middle is RWRP since the two-pickup combinations at position 2 (Bridge and Middle) and position 4 (Middle and neck) are both then hum-cancelling. Since yours will be a HSS, the considerarions are a bit different.
As a general rule, you would not want both neck and middle pickups to be RWRP, since then any neck/middle combinations would not be hum-cancelling. This would be true for both series or parallel combinations of those pickups.
Whether the neck or the middle should be RWRP will probably depend on what coil-splitting options you will have for the bridge HB. The goal should be to maximize the number of hum-cancelling combos overall. Phase switching also throws a wrench in the works to a certain extent, since a hum-cancelling combo will no longer be hum-cancelling iif one pickup is OOP with the other.

Sorry for asking the basics, but I'd like to know (better late then never). When pickup combination is hum cancelling?
I thought that hum cancelling was happening when pickups were in reversed polarity. Don't know what reverse wound is though.
For example, general humbucker is hum cancelling. Does this mean that it has both coils RWRP?

RW and RP are only meaningful in relative terms. That is, only when you're comparing two (or more) coils. The two coils of a humbucker are always opposite both in magnetic polarity and winding direction from one another. If you pick one to be "normal", then you can say that the other is RWRP relative to that. But you can also just as well call the second coil "normal", and then the first is RWRP. Dig?
The same goes for any pair of coils really. You want the neck and middle pickups to be opposite from one another. Whichever one you want to call normal, the other should be RWRP. Unless you plan on some switching scheme that never puts them together in which case it literally doesn't matter or you want them to always be out of phase whenever they are combined, or I guess if you really just want all the hum you can possibly get. This then means that one coil of the HB will the same as one of the SCs, and the other will match the second. IF you intend to split the HB AND combine it with one of the SCs, you'll want to make sure that you're splitting to the coil that will cancel hum. Call the SC "normal", split to the HB coil that is RWRP compared to that.

I thought that hum cancelling was happening when pickups were in reversed polarity. Don't know what reverse wound is though. Polarity without qualification is a little bit vague here: winding direction, being the direction in which the coil's wire is wound around the bobbin at the time of manufacture, is itself a type of polarity -- it has two extremes, which are opposites: clockwise and counter-clockwise. As such a pickup really has two polarities: a magnetic polarity and an electric polarity. The magnetic polarity is determined by the orientation of the magnet(s) within the pickup, the electric polarity is determined by both the winding direction and, the way in which we assign the coil's start and finish wires when wiring it into the guitar. The electric polarity determines the phase of the signal (both of the strings and background hum) that is induced into the coil, whereas the magnetic polarity only determines the output from the strings. Therefore to have two coils be hum-cancelling their electric polarity must be opposite such that the hum induced by one coil is out-of-phase with, and thus cancelled by, the hum induced in the other. Whether or not the coils also have opposite magnetic polarities determines if the signals from the strings are also out-of-phase: reverse electric polarity & reverse magnetic polarity is hum-cancelling and gives the standard (in phase) sound; reverse electric polarity & same magnetic polarity is still hum-cancelling but gives the out-of-phase sound. If you pick one to be "normal", then you can say that the other is RWRP relative to that. But you can also just as well call the second coil "normal", and then the first is RWRP.
Additionally, note that since there are two types of polarity and each has two options there are a total of four possibilities out of which a person (or manufacturer) may choose what is 'normal' (in rare cases this can even vary between different pickups from the same manufacturer). However, since in most cases we can simply reverse the electric polarity at will, by the way in which we assign the coil's start and finish wires in the wiring, this is effectively halved to only two.

Thanks everyone for the replies! It become a little bit clearer. I agree, that the main goal is to have as much hum-cancelling combinations as possible. If neck and middle will be RWRP, they will be hum-cancelling while working together. However, I'm not sure about one thing: what would happen in case SC would work with another humbucker switched on. Let's imagine that neck and middle are not RWRP. For now I'm not looking into OOP combinations. I assume the following: - Bridge (humbucker) + middle: hum cancelling or no?
- Bridge (split) + middle: hum cancelling (depending on coil)
- Bridge (humbucker) + middle + neck: hum cancelling or no?
- Bridge (split) + middle + neck: hum cancelling or no?
Generally, the question is how humbucker would work with one or two single coils, will it cancel the hum?

No. For hum-cancellation, one of the two must be RWRP with respect to the other; as ashcatlt put it, one you call "normal", the second is RWRP. with respect to the first pickup.
On a classic Strat design, positions 2 and 4 are the only combinations of pickups (B + M and N + M, respectively). Fender began using a RWRP pickup in the middle position, thus making both 2 and 4 hum-cancelling.
If, instead, Fender had decided to make the neck pickup RWRP, then the N + M position (#4) would remain hum-cancelling, a RWRP neck paired with a "normal middle". But position 2, B + M, would not hum-cancel.
If you mean the HB with both coils operating, paired with the SC, you'd have (by definition) two identical coils and one opposite to the other two. This will be partially hum-cancelling.
If neither the neck nor middle pickup is RWRP, you will not have hum-cancellation at Position 4 (N + M).
Br HB + M will be partially hum-cancelling Br(Split) + M- depends on which coil of the HB is split off. Br HB + M + N- hum-cancelling only if N or M is RWRP. Br (split) + M + N- could be partially hum-cancelling depending on which coil of the HB is split off.
I'm sorry if some of this is redundant, but I have tried to be clear and precise in language to avoid any misunderstanding. Your last post indicates that you are still not quite understanding the hum-cancellation.

If you consider one combination of magnetic and wiring polarity as 1 (a unit), and the RWRP of that as -1, the math is pretty easy. Just add it up and if it doesn't add to 0, then it's not hum cancelling. Doesn't actually matter if the answer is positive or negative, but the absolute value can give you an idea of how bad things might be. I think you will pretty quickly realize that no combination of an odd number of coils can ever be fully hum-cancelling no matter what each one does. The best you can hope for is the hum of one coil.
If I understand your question, we're assuming the two SCs are alike - neither is RWRP from the other?
In that case we'll call the SCs and the like coil of the HB as 1, and have:
•Bridge (humbucker) + middle: hum cancelling or no?
1 + -1 + 1 = 1 (not cancelling)
•Bridge (split) + middle: hum cancelling (depending on coil)
assuming you choose the appropriate coil of the HB -1 + 1 (yes)
•Bridge (humbucker) + middle + neck: hum cancelling or no?
1 + -1 + 1 + 1 = 2 (not, about twice as bad as any single)
•Bridge (split) + middle + neck: hum cancelling or no?
best case -1 + 1 + 1 = 1 (not)
If one of the SCs is RWRP compared to the other, then you can get the one that adds to 2 to add to 0, but it can't help the 3-coil combinations
Edit - I guess newey ninja'd me, but we said about the same thing. It's important to note that this is all theoretical and best case. Even the ones that "add to 0" won't actually be 100% hum cancelling. How well they actually reject noise will depend on how alike the coils are, and how close they are physically, and luck and which direction you're facing, and whether you're under a cell tower or near a truck stop, and...

I think you will pretty quickly realize that no combination of an odd number of coils can ever be fully hum-cancelling no matter what each one does. Applying a little more maths, we know that isn't strictly true, it would be better to say "no simple combination", or at least "no typical combination". Buried in How to explain Hum-cancelling is a link to a page from JohnH 's old Geocities site, which includes an example of this. It was also further discussed here: 3 pup coil hum-canceling.
Additionally, I find it useful to think of the hum output of a particular combination relative to the strings signal output: a signal-to-noise ratio, of sorts. For example, a single coil has an output-to-hum ratio of 1:1, a pair of normal and RWRP coils wired in parallel and in phase is 1:0, the latter but in series is 2:0. That's particularly helpful when trying to quantify what "partially hum-cancelling" means, e.g. in the case of the bridge humbucker in parallel with the middle pickup, the ratio is 2:1

No. For hum-cancellation, one of the two must be RWRP with respect to the other; as ashcatlt put it, one you call "normal", the second is RWRP. I think that that was exactly what I meant. For example, bridge pickup is off, neck & middle are RWRP and working together. In this case middle is RWRP with respect to the neck, and bridge is off. Aren't they hum cancelling? I'm sorry if some of this is redundant, but I have tried to be clear and precise in language to avoid any misunderstanding. Your last post indicates that you are still not quite understanding the hum-cancellation. I'm trying to understand. This is not redundant rather helpful. As a general rule, you would not want both neck and middle pickups to be RWRP I think that's the message which I have not understood correctly. Please correct me if I'm wrong, but I believe that you meant "both neck and middle" to be RWRP with bridge.

Yes, they will be. Your prior post said they would "both be RWRP", I think both ashcatlt and I were confused by that. The two coils have to be opposite of one another to be hum-cancelling.
No, what I meant (thinking that you were talking of both N and M being RWRP) was that the N and M, if both were RWRP, would not be hum-cancelling with one another, i.e., the N + M combo would hum.
If both N and M were RWRP, a combo of either N or M, paired with one bridge coil, would hum-cancel with the bridge coil that was opposite, but not with the other bridge coil, which would then be the same as both N and M (all RWRP in our example).

From what I've understood, RWRP concept works the best (in scope of hum cancelling) when two pickups are the same (manufacter, impedance, magnet type etc.). If two single coil pickups are different, for example, a Jaguar pickup with 6.8K impedance and a P90 pickup with 6.1K impedance, is there sense in having one of them RWRP with respect to the other?

identical pickups will hum cancel better than dissimilar ones, but even with dissimilar pickups some noise cancellation will happen. So it does make sense if one has the option to use one RWRP pickup, that is, if you're going to buy new ones anyway, might as well get a RWRP for one of the two.

There's a nice but subtle outcome when combining two pickups of similar construction but different number of wire turns. They too can hum-cancel very well in simple parallel combos of two, if one is RWRP with respect to the other.
The added resistance of the one with greater winding compensates for its tendency to pick up more hum signal than the other. This applies in typical sets of a certain type, but where each pickup has different number of turns. The reasoning also explains how some combos of three pickups can be humcancelling.

The added resistance of the one with greater winding compensates for its tendency to pick up more hum signal than the other. This applies in typical sets of a certain type, but where each pickup has different number of turns Emphasis on the parallel part. Lets look at an example: take two pickups: a 'reference' coil, A, with R_A = 1 & \text{Hum Output}_A = 1 and second larger RWRP coil, B, with R_B = 2 & \text{Hum Output}_B = -2 . The hum output for the series combination (A * B) is just a simple sum: \begin{aligned} \text{Series Hum Output} &= \text{Hum Output}_A + \text{Hum Output}_B \\\\ &= 1 + (-2) \\\\ &= -1 \end{aligned}
We still have some amount of hum, but in comparison to the worst non hum-cancelling arrangement (where Signal Output = Hum Output), we have about a third of expected the hum (since the Signal Output of the above would be 3). Whereas, in parallel (A + B): \begin{aligned} \text{Parallel Hum Output} &= \text{Hum Output}_A \times \frac{R_B}{R_A + R_B} + \text{Hum Output}_B \times \frac{R_A}{R_A + R_B} \\\\ &= 1 \times \frac{2}{1 + 2} + (-2) \times \frac{1}{1 + 2} \\\\ &= \frac{2}{3} - \frac{2}{3} \\\\ &= 0 \end{aligned}
We have total hum-cancellation (or a close as is practically possible). N.B. the above works where the values of one coil are any multiple other, that is even a non-integral multiple -- what matters is how close to equal the two ratios of hum output to resistance are for the two coils.
For example, with a standard set of Strat pickups (with a RWRP middle pickup) the only in phase, essentially parallel, combination of all three coils that is hum cancelling is: Middle + (Bridge * Neck). That is very similar to what we have above with coils A & B, though it might be easier if we imagine our second larger, B coil had a centre coil tap, then we can see that it is just two similar coils joined in series, very much like the Bridge & Neck in the Strat example. It just happens to be that these two coils are wound wound on separate bobbins, rather than concentrically.

The hum output for the series combination (A * B) is just a simple sum Whereas, in parallel (A + B) we have total hum-cancellation (or a close as is practically possible). That's very nice and informative explanation. I wonder, why something like this is not included to the owner's manual of any musical instrument having pickups? That's JohnH 's Geoicities resource is pretty interesting, thanks for sharing. I didn'n know it so I spent several nights investigating it. I'm not sure if I understand hanging coils issue properly, but I can see in cancelhum page the following explanation of hum-cancelling concept: Am I right that that statement is applicable to the coils whose "+" or "-" wires are connected to the output? And if these wires are connected to the ground, that's not an issue? In particular, would like to understand that schematics from the twinpickups page: Let's imagine we're on the first possible switching option: Neck pickup in-series and in-phase. I understand, that in this case SW2 does not affect at all, according to the description. But if we switch it to another position, won't we have hanging coils issue on the bridge pickup? In order to answer this, tried to redraw the schematics. I've eliminated vol/tone pots (I hope that I've done in properly...) and moved SW2 to "X" position. Here's what I got: From what I can see, bridge pickup in series is connected to the ground. I'm not sure, is this the same as "hanging coils"?

Am I right that that statement is applicable to the coils whose "+" or "-" wires are connected to the output? Correct. I don't think it's explicitly stated anywhere above, but there isn't really a fundamental difference between the ends of a pickup coil, as such "+" and '-' have no innate meaning to a (passive) pickup, it is just a convention to help determine which way a coil ought to be connected in order to be in phase with others. (The exception being pickups such as vintage style PAFs, Tele pickups, or others where the connection to one end of the coil also has the duty of being used for shielding, and thus should always be the wire to ground.) No. ( Unless you have an abnormally high concentration of magic in or around your guitar.) On a more serious note, below is the best individual post I could find on the subject: Hanging from hot....causes noise, but its not a show stopper. To understand the issues, try this test, with a guitar cable, an alligator clip wire, and an amplifier. Turn up the amp, with nothing plugged in – it should still be fairly quite. Plug in the cable, and if it is a good one, there will be a small amount of buzz but not too much. In this state, we have a long ‘hanging from hot’ cable, which is the inner core. But it is inside the outer grounded screen acting as a shield. Conclusion: Shielding is good Connect alligator clip wire to the grounded outer part of the jack plug at the free of the cable. No difference, anything grounded makes no noise in this case. Now move the alligator clip wire to the jack tip. It is now hanging from hot and adds a loud buzz because it is not shielded. Now test the idea that shunting both ends of a hanging from hot item makes a difference. With one end connected to the tip, compare the buzz either with the other end also connected to the tip, or just clipped to the outer insulation nearby. Ie, physically, it is in the shape of a loop connected to the hot, but you try it both electrically connected as a loop, or not . The result is that they are the same, there is no difference in buzz whether or not the wire has both ends to hot or just one end. The hypothesis derived from this is that for a pickup, if you have a hanging coil whether or not you shunt it will not affect the buzz created, but short wires and shielding will help. The way I see this, the hanging from hot item is like one plate of a capacitor, the other being the rest of the planet. Whether this element forms a loop in its local self is not relevant to the charges that are induced in it by outside emfs. rather, what is important is its overall physical dimensions, and any protection it gets from shielding My LP has a series option, and if the neck pickup is turned down when in series mode, so just the bridge is sounding, then it s ‘hanging from hot’ and there is a very slight additional buzz as compared to a standard bridge only setting. Its OK though, but worth avoiding when possible. sumgai, newey, reTrEaD, JohnH, ashcatlt, and others who have been here far longer than me, though the issue of pickups hanging from hot has been discussed extensively I couldn't find a definitive thread dedicated to the subject, is there one?

I've never found a truly 'definitive' thread on the subject. mostly tangent conversations within threads regarding other issues. But the subject is rather old. Before reTrEaD , before newey , before sumgai , before ashcatlt . But not before JohnH as there wasn't much that happened before him. Aside from occasional visits by wolf , John is the last remaining regular from the 2005 crew currently active on GN2. If you do a search of the phrase 'hanging from hot' and include the unHoly Trinity from the earliest days ( ChrisK , JohnH , and UnklMickey ) as the 'who', you can look through the posts on the subject going all the way back to 2005. One title from 2007 seems promising pup hanging from hot but I wouldn't characterize the thread as being definitive.

I seem to recall someone saying they did some testing, and saw no discernible difference in noise in a guitar with a coil hanging, compared with the same guitar with that same coil completely disconnected. But it's only a vague recollection from years ago.
And, IIRC, the criticism was that you wouldn't necessarily hear a difference unless one were in an environment with more electrical noise than was present during the testing, e.g., a bar with neon beer signs, fluorescent lamps, etc.

I must admit that at the end of the day, I will always go with what sounds good and not be too concerned about cancelling all the hum. I do shield my guitars, and I do eliminate hanging from hot situations to minimize the noise, but I have never been impressed with a guitar tone due to its "lack of noise".

The magnetic polarity is determined by the orientation of the magnet(s) within the pickup, the electric polarity is determined by both the winding direction and, the way in which we assign the coil's start and finish wires when wiring it into the guitar. All makes sense to me. So here's a question: does winding direction really matter? Maybe these two sub-questions are s different way of asking the same thing: Does the sound produced by a coil depend on whether its start is assigned to ground versus hot? For a pair of coils, will the sound change if we simultaneously swap both of their ground and hot assignments? Same question for multiple coils ( all).

Fender didn't start using RWRP middle pickups until the early 1970's, so there are those "vintage Strat" types who argue that none of the pickups should be RWRP for the true "vintage tone". Of course, since the point of a RWRP pickup is to reduce noise, when in combination with a non-RWRP pickup, the vintage set-up will be noisier than with a RWRP. Typically, on regular SSS Strats, the middle is RWRP since the two-pickup combinations at position 2 (Bridge and Middle) and position 4 (Middle and neck) are both then hum-cancelling.

As a general rule, you would not want both neck and middle pickups to be RWRP, since then any neck/middle combinations would not be hum-cancelling. This would be true for both series or parallel combinations of those pickups. Whether the neck or the middle should be RWRP will probably depend on what coil-splitting options you will have for the bridge HB. The goal should be to maximize the number of hum-cancelling combos overall. Phase switching also throws a wrench in the works to a certain extent, since a hum-cancelling combo will no longer be hum-cancelling iif one pickup is OOP with the other.

mitch88- Sorry, didn't intend for you to spend an hour scratching your head. We use the "OOP" abbreviation for "out-of-phase quite a lot around here, and I forget that not everyone gets the nomenclature. To complete the thought, you may also see "POOP" for "parallel out-of-phase" or "SOOP", "series out-of-phase". We also use "HOOP" for "half out-of-phase" which is perhaps descriptive more than technically correct- one coil of the combination is partially bypassed by a capacitor.
