The Seymour Duncan Brandon Ellis Dyad represents cutting-edge pickup innovation informed by one of modern metal’s most technically accomplished guitarists. Released in 2024 as a signature design for Brandon Ellis of The Black Dahlia Murder, the Dyad features a revolutionary dual-coil design that combines the North coil of Seymour Duncan’s Crazy 8 with a hotter South coil based on the Parallel Axis Trembucker Distortion. The result is a high-output pickup with sizzly bite, articulate attack, and the aggressive-yet-articulate character that modern technical metal demands.

Sound & Tone
The Brandon Ellis Dyad brings innovative design philosophy to modern metal. The dual-coil approach—combining different North and South coil characteristics—creates tonal complexity that single-personality pickups struggle to achieve. In moderate gain contexts, the articulate North coil dominates, delivering note separation and clarity that suits cleaner metal tones. As gain increases, the hotter South coil comes forward, providing aggressive character and sustain that modern metal requires.
The pickup’s most distinctive characteristic is what many players describe as a “sizzly bite”—a combination of aggressive treble presence and tight transient response that cuts through dense mixes with remarkable clarity. This isn’t harsh or thin, but rather articulate and musical. Even in the heaviest distortion, individual notes remain defined; complex chord voicings stay intelligible; fast picking maintains rhythmic precision.
The high-output characteristic means the Dyad responds aggressively to amp gain stages. However, unlike some high-output pickups that compress dynamics into uniformity, the Dyad maintains responsiveness to playing technique and dynamics. Harder playing yields snappier attack; softer touch produces controlled articulation. This responsiveness is crucial for technical metal musicians who use dynamics and playing precision as essential tools.
Who Should Buy the Seymour Duncan Brandon Ellis Dyad
Technical metal and progressive metal musicians should make the Brandon Ellis Dyad a priority. Players in bands influenced by The Black Dahlia Murder or seeking similar aggressive-yet-articulate tone will find the Dyad revelatory. The pickup works exceptionally well in downtuned applications where its tight transients and articulate response prevent muddiness.
If you value innovation and want pickups designed specifically for modern technical metal’s advanced playing techniques and extreme contexts, the Brandon Ellis Dyad represents state-of-the-art design. This is a signature pickup developed by a working professional musician in one of metal’s most demanding bands—it delivers results.
Tone Tips & Best Pairings
The Brandon Ellis Dyad represents a collaboration between Seymour Duncan and guitarist Brandon Ellis of Whitechapel, focusing on modern metal pickups that maintain articulation and clarity even under extreme gain and downtuning. The Dyad’s distinctive characteristic is its implementation of the Parallel Axis technology, a significant departure from traditional humbucker design that alters how the pickup responds to string vibration and overall signal generation. Rather than relying on the conventional pole piece/magnet configuration, the Parallel Axis technology uses differently-oriented magnet arrays that capture string vibration with greater sensitivity to specific frequency ranges. This results in pickups that behave differently from traditional humbuckers in ways that significantly impact tone and responsiveness.
The Brandon Ellis Dyad bridges (neck and bridge configurations available) feature this Parallel Axis technology to deliver tight, controlled output that works exceptionally well for metal applications requiring definition rather than maximum compression. The bridge pickup’s output sits around 16k—comparable to other high-output designs—yet achieves its aggression through frequency emphasis rather than pure output magnitude. This means the Dyad’s signal prioritizes certain frequency ranges over others, creating tone shaping characteristics that differ from conventional high-output pickups. The result is a tone that feels aggressive and present without the compressed, flattened character of some high-output alternatives. Players transitioning from standard humbuckers to the Dyad often describe the experience as “more controlled” aggression—the pickup’s output drives amp gain sufficiently while maintaining note-to-note clarity.
Parallel Axis Technology Explained
The Parallel Axis technology at the heart of the Dyad involves magnet orientation and pole piece configuration that differs fundamentally from traditional humbucker architecture. Rather than stacking magnets vertically (one above the lower coil, one below the upper coil), the Parallel Axis design orients these magnets differently, creating magnetic fields that interact with string vibration in novel ways. This configuration emphasizes specific frequency ranges—particularly the upper mids and highs that define articulation in metal applications. The result is a pickup that feels less compressed than comparable-output designs while maintaining sufficient signal to drive high-gain amp stages into saturation. The technology isn’t merely cosmetic marketing; experienced players report measurable differences in responsiveness, pick attack definition, and overall clarity compared to traditional humbucker designs.
Amp Gain Settings & Metal Rhythm vs. Lead Use
The Brandon Ellis Dyad’s Parallel Axis technology affects ideal amp gain staging. Set your amp’s gain to approximately 6-7 rather than the extreme 9-10 that some high-output pickups require; the Dyad’s frequency-focused output often achieves satisfying saturation at more moderate gain levels. This has practical benefits: lower amp gain means greater responsiveness to your guitar’s volume control, more natural tube breakup (if using a tube amp), and superior definition in rhythm playing. The Dyad rewards controlled picking and technique precision—sloppy playing sounds sloppy through this pickup more than it does through compressed, high-output designs that flatten inconsistencies. For metal rhythm work, the Dyad’s tight character and definition excel, allowing complex chord shapes and muting patterns to remain articulate and clear. For lead work, the Dyad’s responsiveness to dynamics and picking technique makes it exceptionally expressive—players can shape tone through pick attack and string pressure rather than relying solely on gain structure.
Standard Tuning vs. Drop Tuning Performance
The Brandon Ellis Dyad maintains exceptional clarity across standard tuning and extreme downtuning scenarios. In standard tuning paired with standard gauge strings (0.46-0.56), the Dyad sounds tight and aggressive with excellent definition. Transitioning to drop tuning (Drop D through Drop A) with heavier gauge strings (0.68-0.80), the Dyad’s Parallel Axis technology prevents the typical loss of clarity and definition that plague other pickups in downtuned applications. The pickup’s 16k output remains usable and controlled rather than becoming compressed or muddy—a crucial advantage for modern metal applications. Players pursuing extreme downtuning should set pickup height slightly higher (approximately 2.5mm treble, 2.8mm bass) to maximize output while maintaining the Dyad’s characteristic clarity. Use heavier string gauges (0.80+) with extreme downtuning; lighter gauges sound thin and overly compressed through the Dyad’s frequency-focused response.
