JUGGERNAUT HUMBUCKER
The Juggernaut is a signature humbucker set designed with Periphery guitarist Misha Mansoor, combining massive low-end weight, aggressive attack and exceptional clarity with the dynamic response needed for modern progressive playing.
The bridge pickup combines Alnico V and Ceramic VIII magnets with symmetrically hand-wound twin screw coils to deliver a powerful and focused response. Its tight, controlled bass and substantial midrange provide exceptional definition through complex chord voicings, while the rich, vocal high end maintains clarity and articulation under heavy gain.
The neck pickup uses a custom-sized Alnico V magnet to produce a full, musical response with excellent dynamics and articulation. Clean tones are broad and powerful, while higher-gain sounds remain fluid and defined, making the pickup equally effective for melodic leads, sustained passages and detailed chord work.
The Juggernaut is designed to combine the tightness and attack associated with ceramic pickups with the dynamics and musical response of Alnico. It responds naturally to picking intensity, remaining full and controlled with a lighter touch while becoming increasingly aggressive when driven harder.

HALCYON HUMBUCKER
The Halcyon is a high-output signature humbucker set developed with Spiritbox guitarist Mike Stringer, designed to deliver massive modern tones, exceptional clarity and consistent string-to-string response across low tunings.
The bridge pickup uses a twin-blade design and three custom-sized ceramic magnets to provide exceptional string balance while tightly controlling the low end. Its high-output wind delivers an aggressive attack, powerful midrange and substantial low-end weight, giving single-note riffs impressive thickness while keeping ultra-low chugs tight and articulate.
The neck pickup uses a more moderate wind paired with an Alnico 5 magnet, providing greater dynamic headroom and a woody, bright character without becoming harsh. Its articulate response works particularly well for clean and ambient tones, while combining naturally with the bridge pickup for distinctive modern clean sounds.
The twin-blade construction provides even string-to-string balance regardless of string gauge or tuning and is particularly practical for multi-scale instruments. Both pickups are also designed to deliver highly effective coil-split and parallel tones, providing additional tonal flexibility beyond their primary high-output voices.
The Halcyon set is particularly suited to players working in heavily detuned environments who require the power and immediate response of a high-output pickup while retaining the clarity and consistency needed to remain defined within dense mixes.
APPLICATIONS
Modern Metal, Progressive Metal, Djent, Alternative Metal and other modern high-gain playing styles.

APACHE SINGLE COIL STRAT & STORMY MONDAY HUMBUCKER SET
APACHE SINGLE COIL STRAT
Pure, full-bodied early-'50s Strat tone with exceptional dynamics.
The Apache is a full-bodied early-'50s single coil set delivering exceptional natural sustain and low string pull from its Alnico III magnets.

BLACK HAWK HUMBUCKER SET
The power and clarity of an active pickup, with the tone, dynamics and responsiveness of a passive.
The Black Hawk is a radical-looking humbucker designed for players who want the output and transparency of an active pickup without sacrificing the character, dynamics and control of a passive design. Best of all, it delivers this performance without the need for batteries.
Each coil features specially annealed, nickel-plated steel blades that provide an even magnetic field across the strings, ensuring excellent string-to-string balance and a consistent response across the entire fretboard.
While its DC resistance may appear moderate on paper, the specially designed coils, blade construction and custom-calibrated magnets deliver substantial output without compromising dynamics. The Black Hawk remains highly responsive to pick attack and volume adjustments, allowing players to move effortlessly between clean, driven and high-gain tones.
The low end is deep, tight and exceptionally fast-tracking, making it ideal for precise riffing and lower tunings. High notes remain full and powerful, even high up the fretboard, supported by broad mids and solid, articulate highs. Despite its high-output capability, the overall response remains clear and detailed without becoming harsh or clinical.
Hand scatter-wound with 42 AWG Heavy Formvar wire, the Black Hawk is available with different magnet configurations to tailor its response. The bridge pickup can be powered by either a trio of Ceramic magnets for maximum speed, aggression and output, or a trio of Alnico V magnets for a smoother, more organic response. The neck pickup uses Alnico V for a clear, dynamic and expressive voice.
From Jazz and Fusion to Hard Rock and the most extreme forms of Metal, the Black Hawk offers a vast range of contemporary tones with exceptional clarity, power and control.
