At a glance
Six designs cover almost every electric guitar built since the 1930s. The same coil-and-magnet recipe, with different proportions:
| Type | Sound | Output | Hum-cancelling? | Typical DC resistance | Best for |
|---|---|---|---|---|---|
| Single coil | Bright, clear, articulate | Low–medium | No (paired positions cancel) | ~5.5–8 kΩ | Country, funk, surf, blues, indie |
| Humbucker | Thick, warm, midrange-forward | Medium–very high | Yes | ~7.5–16 kΩ | Rock, blues, jazz, metal |
| P90 | Gritty, raw, in between single & humbucker | Medium–medium-high | No | ~7.5–9 kΩ | Garage, classic rock, soul, punk |
| Mini humbucker | Tighter low end, more top end than full humbucker | Medium | Yes | ~6.5–9 kΩ | Roots rock, jazz, archtop tones |
| Filter’Tron | Chimey, clear, open | Medium | Yes | ~4–5.5 kΩ | Rockabilly, country, clean-break-up rock |
| Active | Flat, consistent, low-noise | High (preamp) | Yes | n/a (active) | Metal, modern hard rock, studio |
Each design is covered in detail below.
Single coil
One coil wound around six pole pieces (one per string). The original electric guitar pickup — introduced in the 1930s and standardized by Fender on the Telecaster and Stratocaster.
- Sound: bright, clear, articulate, with strong top end and good note separation.
- Noise: picks up 60‑cycle hum from lights, transformers, and wall power. Adjacent positions on a Strat (2 and 4) wire two singles in opposing polarity to cancel that hum.
- Examples: Fender Tele bridge/neck, Strat single coils, Lipstick pickups (Danelectro), Jazzmaster pickups (wider, flatter coil).
Humbucker
Two single coils wired in series, with reverse polarity and reverse winding. The signal from the strings adds together; ambient hum cancels. Patented at Gibson by Seth Lover in 1955; commercialized as the PAF.
- Sound: thicker, warmer, louder, and darker than a single coil. Strong midrange. Pushes a tube amp into overdrive at lower settings.
- Noise: the two coils cancel hum, hence the name.
- Examples: Gibson PAF, ’57 Classic, Burstbucker; Seymour Duncan SH‑1, ’59; DiMarzio Super Distortion.
- Variants: coil-split (one coil only, single‑coil-ish tone) and series/parallel switching expand the available voicings.
P90
A single coil with a wider, flatter bobbin than a Fender single, mounted between two bar magnets. Gibson’s standard pickup before the humbucker, still loved on Les Paul Specials/Juniors and SG Specials.
- Sound: thicker and grittier than a Strat single, brighter and more aggressive than a humbucker. The classic “rock and roll” pickup.
- Noise: single coil — hums like one. Stacked or sidewinder “hum-cancelling P90” designs exist.
- Form factors: “soapbar” (rectangular) and “dog-ear” (with mounting tabs).
Mini humbucker
A narrower humbucker with smaller coils. Used on Gibson Firebirds, ’70s Les Paul Deluxes, and many Epiphone archtops.
- Sound: tighter low end and more top-end clarity than a full-size humbucker; still hum-cancelling. A useful middle ground between a P90 and a PAF.
- Drop-in option: some are sized to fit standard humbucker routes for easy swaps.
Filter’Tron
Gretsch’s humbucker, designed by Ray Butts in 1957. Smaller, more open coils than a Gibson humbucker, with a different magnet structure.
- Sound: chimey and clear with a strong top end, but still hum-cancelling. A favorite for rockabilly, country, and clean-into-overdrive rock.
- Examples: Gretsch Filter’Tron, TV Jones Classic, TV Jones Magna’Tron.
Active pickups
Pickups with very low coil output and a built-in preamp powered by a 9V battery in the body cavity. The preamp does the heavy lifting that high-turn passive coils otherwise would.
- Sound: consistent, low-noise, with a flat frequency response that responds well to high gain. EMG 81 / 85 are the canonical metal pair.
- Tradeoffs: requires a battery; less “dynamic touch sensitivity” than a high-quality passive pickup; pots and caps are different (typically 25k volume, 25k tone).
- Examples: EMG 81/85/60, Fishman Fluence, Seymour Duncan Blackouts.
