Fralin Pickups: What does “Resistance” mean for pickups?

Interesting, huh? Be careful not to touch the pickup winding wires. Gibson P pickups and their third-party copies have a coil shape similar to the Jazzmaster. Fralin Pickups is a small US company that makes extremely high-quality pickups to order. Here are some of the most common:. Hey Szymon, Great question. On a single-coil pickup, these are sometimes screws, and they can easily be individually raised or lowered with a screwdriver to adjust the output of individual strings.


The heart of an electric guitar's tone is in its pickups. Place the pickup on a flat surface and anchor its lead wires with tape. If the pickup has more than two lead wires and you have trouble identifying which you should meter, trace the wires back to the pickup: The wires that directly contact the pickup windings are the only ones that will give you the pickup's resistance. If you have an analog meter, it is necessary to establish a zero reading. Touch the meter's black probe to the bare wire at the end of the negative pickup lead, usually the black wire. Do not touch any conductive metal, either the probes or the pickup leads, with your fingers. Doing so will measure your body's resistance and skew your results. Watch the meter's needle or digital readout. An analog meter's needle will take a moment to settle on the correct reading, but a digital meter will give immediate results. The higher the resistance, the hotter the pickup will sound. If there is no reading, the pickup may be damaged.


This compares to Gibson, which started using double coil Humbucking pickups in Single coil pickups have a source slab of wound wire around magnet s. Single coil pickups are easily influenced by outside noise. This would include 60 cycle hum and fluorescent lights.

Single coil pickup ohms pickup: This type of pickup has two single coils combined into one unit. Each coil is reverse wound so that the hum from first coil cancels the hum from the second. The two coils are wired in series so the read article resistance is additive, producing a "hotter" and quieter pickup if the two coils were wired in parallel, the total resistance is half the sum of the resistances of each individual coil, assuming both coils are about the resistance.

In either case parallel or seriesthe hum does cancel, hence the name "Humbucking". Parallel is why the "in-between" setting used on a Stratocaster combining the middle pickup with the neck or bridge pickupdoes not produce a Humbucking pickup sound. Also, the in-between switch setting on a Humbucking two pickup Gibson is less powerful than each pickup individually. The two Humbucking pickups are combined in parallel even though the two coils of each pickup are in seriesthus giving the average of the two pickups divided by two.

Interesting, huh? Ohms: messure of resistance. The longer the single ur cool wire and more turns used, the higher the resistance. Also the higher the resistance, the louder or "hotter" the pickup.

But be aware, higher resistance comes at a cost: lose of treble frequencies. This is why single coil pickups have more treble and less output than Humbucking pickups which use two coils.

Hence Humbucking pickups have more mid-range and are "hotter". Also this is why single coil pickups single coil pickup ohms are wound with tons of wire to approach Humbucking ohms don't sound very good. Turns or Windings: this is the number of turns of wire used on the pickup. Fender had a mechanical counter attached to their winding machines that counted the turns.

These vintage pickup winding machines were manually run by humans, so the exact number of turns can vary from pickup to pickup. Winding Direction WD : This is the direction in which the pickup was wound. Seymour Duncan's terminology best describes this: TL means the top of the pickup bobbin is facing left. TR means the top of the pickup bobbin is facing right. TG means the top of the bobbin is turning away from the winder.

TC means the top of the bobbin is turn towards the winder. Reversing the winding on a pickup will reverse the phase of the pickup. Magnetic Polarity MP : This is the magnetic polarity on the top side of the pickup. All magnets have two poles: north and south. Reversing the poles of a pickup will also reverse the phase of the pickup. They are "sand cast", and hence have a crude, rough look with pitting left from the sand cast. The tops of the magnets are ground flat. Usually the magnets have one end chamfered, which helps guide the magnet thru the vulcanized fibre flatwork this is very noticible on Strats, and non-existant on pre Teles.

Pre magnets are inconsistent in diameter, ranging from. But for the most part, they fit very tightly in the flatwork. Starting inthe diameter seemed to get narrower by a few thousands of an inch. Hence the flatwork did not fit as tightly around the magnets. This causes many and later Fender pickups to "warp", where the flatwork will actually buckle and curve. Mid's magnets have a smoother edge, and eventually the chamfering of the pickups stopped entirely by the early 's.

Flat Visit web page this is the vulcanized fibre portion of Fender pickups. This material holds the magnets in place and the windings of the pickups then go around the magnets. Pre-March Fender pickups used black vulcanized fibre flatwork. After approximately Marchthis changed to a light gray vulcanized fibre. Then again in the early 's, it switched back to black vulcanized fibre.

Hand Winding: This single coil pickup ohms also known as single coil pickup ohms winding", where the pickup wire is wound on the bobbin in a random manor. This is how Fender pickups were wound prior tosince it continue reading a semi-manual operation, using a machine to turn the pickup bobbin, while a worker would guide the wire onto the turning bobbin.

InFender changed to "machine winding", as it is a completely automated process. Machine winding takes away much of the single coil pickup ohms of the pickup. A lot of the sound of old Fender pickups is due to the random layering and variable winding tension of the wire, which effects the tone. With machine winding, this is all very sterile and consistent. If you see the chart below, notice how consistent the Strat pickup specs get when machine wound after Not much variance from year to year with machine winding.

Insulation: this is the surface coating that is baked on to the wire that prevents the turns of the pickup from shorting out. We are all familiar with the insulation on larger wire: usually it's a PVC plastic coating that you have to strip away when connecting. But on the extremely thin wire used in pickups, this insulation is a bake-on coating. There are several different type of baked-on insulation: Formvar, Plain Enamel, or Poly. Fender used Formvar till about Marchwhen they switched to Plain Enamel.

This happened at about the same time they switched from black flatwork to light gray flatwork. Wire Outside Diameter OD : this is the outside diameter of the winding wire, not including the insulation. The thinner the wire, the higher the resistance ohms. Though this has less of an effect on resistance compared to the number of windings. Wire Gauge : this is the gauge of wire as advertised by the wire manufacturer. Fender basically used 42 gauge wire for everything but the Telecaster neck pickup 43 article source. Note the actually outside diameter OD varies partnersuche polen deutschland even though it's the same gauge.

As the gauge number increases, the OD of the wire decreases 42 gauge wire is thicker than 43 gauge wire. Potting : dipping a pickup in wax to seal the windings to minimize vibration so the pickup feedbacks less and is not "microphonic".

There are probably a lot of little factors that make the older Fender pickups sound so good. Not a single link of these factors will change the tone significantly. But when all added together, the sum of the parts is better on older vintage Fender pickups.

These factors would include: Magnets: pre Fender pickups used larger diameter magnets and were here casted. Also vintage Fender magnets are Alnico and not Ceramic. Finally, as time goes on older magnets lose some of their power. The less power the magnets have, the better the strings can here. Powerful magnets can actually pull the strings towards the pickup, dampering the vibrations.

So there needs to be a balance, because you don't want too strong or too weak magnets. So maybe after 30 years, the magnets are at their "ideal" power, thus producing "ideal" tone. Another thing that is different is the "stagger" pattern. That is, the height of the individual magnet pole pieces. For example, today no one uses a wound third G string. But prior to Hendrix, most players did.

To compensate for this, the fixed magnet read article were different on older Fender pickups. Windings: handwound pickups like pre Fenders seem to sound better. It's hard to say why, but the scatter-winding pattern and tension at which the wire was wound was apparently ideal on pre Fender pickups. The handwinding tonal difference may be due to a lack of distributed capacitance when scatter-wound. Wire Insulation: the insulation on the windings of vintage Fender pickups article source different chemical composition than newer wire.

Even though the gauge of the actual wire is the same, the thickness and composition of the insulation is different. This changes the total size of the wound windings. This in turn changes the inductance and capacitance of the pickup, and hence the tone. Fender used Formvar insulation till about March Then they switched to Plain Enamel insulation. Pots: the older potentiometers used have wider tolerences than newer pots.

This may sound dumb, but it could change the tone slightly. And they also used nitrocellulose finishes that were applied very thin. Also the wood itself is older and different than wood today less polution back then means "cleaner" wood.

This will also effect tone. Time: even if all the above are paid attention to and duplicated, time is something that just can't be made up for. Maybe they sound better because they are just older Why do Vintage Fender Pickups Die?
