THE QUADRO HUMBUCKER: A HYBRID MULTI-VOICE SONIC BEAST
Double P90 coils with four magnets fused into a high-powered hybrid humbucker. This multi-voice sonic beast delivers an entirely new sound profile, blending the deep low-end thump of a traditional humb with the defined mids and crisp, detailed highs of a vintage P90 vibe.
- Dual-P90 Architecture: Fuses two distinct P90 coils into a humbucker format.
- Quad-Magnet Power: Utilizes four magnets for enhanced output and tone.
- True Humbucking: Delivers classic hum-canceling performance with a unique sonic footprint.
The QUADRO eliminates the typical humbucker muffled sound, delivering pristine note separation and crystal-clear chord clarity. Super punchy, responsive, and ultra-quiet, this multi-voice pickup excels across a broad spectrum—cutting through the mix on old-school blues-rock solos and delivering massive, noise-free power for modern high-gain heavy metal riffs.
THE STORY BEHIND THESE PICKUPS
What happens when you merge two P90s into a single design? This challenging innovation turned out to be a massive success, yielding a distinct sonic signature that breaks the mold of traditional pickup categories. It creates an entirely new sound profile and a completely unique tonal character unlike any standard pickup you have ever heard. Instead of a traditional single magnet, we resolved to use four—which inspired its name. This configuration unlocks major hum-cancellation benefits alongside an immense upgrade in output power and tonal richness. The result is a hybrid beast—part P90, part humbucker—that offers the absolute best of both worlds.
This multi-voice pickup delivers a broader tonal palette than standard humbuckers, eliminating their typical muffled sound. It is super punchy and responsive, making it easy to inject real feeling into your playing. The design integrates advanced modern technology while honoring the legendary 1950s and 1960s tonal heritage of Fender and Gibson. This versatile pickup excels across a broad spectrum, ranging from traditional blues-rock to modern heavy metal where exceptional noise reduction is vital.
Engineered for musicians exploring uncharted sonic territory, our QUADRO Humbuckers blend the deep, low-frequency impact of a traditional humbucker with the defined midrange and sparkling, detailed highs of a P90. This versatile design delivers exceptional clarity for lead work while injecting authoritative weight into chords and power to huge high-gain riffs.
A traditional humbucker features one bobbin with adjustable screw poles and another with fixed slug pole pieces. From an engineering standpoint, this asymmetrical design is fundamentally the wrong approach if your primary goal is to eliminate noise.
At first glance, it seems remarkably straightforward: make two identical bobbins, and there's no hum or noise. However, two elements come into play. First, the signal enters one coil and exits the other, resulting in a timing discrepancy as it travels a particular distance. Second, two coils capture not quite similar vibrations from strings. The coils are placed side by side, allowing them to pick up vibrations from different zones of the string. You may observe that when you pluck a string near the neck pickup, the sound is fuller and louder than when you pluck the same string at the bridge.
Our approach to producing Strat and Tele singles, in which we match coils for hum elimination while preserving the full spectrum of desired sound, has proven its efficiency. We decided to match the coils in various combinations and realized we could adjust the sound spectrum and noise levels. However, there's one significant disadvantage to this technology: it's very tedious and time-consuming work. Electronic measurement tools are of no use here. Only human ears can pick up the right balance. The product has to be made by hand and then meticulously ear tested and matched. This is craftsmanship at its finest.
NOISE CANCELLING TECH: WHERE ART MEETS SCIENCE
Great vintage pickups breathe. There is no other word for it. They open up and let the instrument speak, warm, full, dynamically honest. The warmth isn't just a frequency curve, it's a quality of harmonic presence that makes notes feel complete rather than skeletal. The fullness isn't about volume, it's about how the pickup captures the full spectrum of string vibration rather than just the fundamental and a few select overtones.
After a lot of testing and real study of how magnets behave over time and under string tension, the goal here was to recreate that quality: clear, immediate, expressive. Not a simulation of vintage tone but a faithful reconstruction of what actually made those pickups feel so alive.
When you play, you want the note to bloom the way it does when you hear a great acoustic guitar in a good room. That bloom, that sense of the sound expanding and then slowly decaying, that's what vintage tone means to us.
That's what we were after.
VINTAGE SOUND CHARACTERISTICS
Magnet quality plays a critical role in tone. Inferior modern magnets can restrict string vibration and produce dull or harsh results.
Through extensive testing and deep study of magnetic behavior, we've worked
specially manufactured magnets designed to replicate the composition and behavior of vintage originals. This helps achieve the characteristic frequency response and feel associated with classic pickups - clear, dynamic, alive.
The result is a tone that feels immediate, musical, and responsive to your every touch.
Every component is considered, every choice deliberate.
The enduring appeal of classic PAFs lies in their dynamic relationship with the guitarist.
Kinetic PAFs interact directly with your playing style, shifting effortlessly from aggressive bite to clean tones, delivering powerful grit under a heavy hand, yet turning crisp and clear with lighter strokes.
Here is what that means in practice. When you play with a light touch, you get the glassy shimmer and natural compression of a lightly struck string. The note has space around it, room to breathe. When you attack harder, the pickup doesn't clamp down or get brittle, it translates the force into more output without losing the harmonic integrity. The note sustains longer because the string is still vibrating cleanly. The overtones stay present rather than collapsing into a flat, compressed blob.
Everything from magnet selection to winding patterns is engineered to give you perfect string-to-string balance and unmatched responsiveness. This ensures every ounce of your personal touch shines through. If you prioritize expressive playing, this flawless guitar-to-player connection is vital—because when your instrument actually sings with you instead of fighting your every move, it completely transforms your tone, technique, and overall joy.
Adjusting the coils is just the first step. Providing proper shielding and grounding is the second. To maximize effectiveness, multilayer alloys of several materials must be employed. Copper is effective at preventing EMI at specific frequencies, while nickel, silver, and aluminum are efficient at protecting against the other range of frequencies.
The secret to a completely quiet ride? The metal cover. To make a humbucker truly noiseless, the cover is an indispensable shielding element that cuts down hum and noise by a massive 30% to 40%.
