MortalCoil delivers three precision-engineered voices: a tight, aggressive modern metal MC1 voice with fast, controlled attack, authentic JB and Jazz-inspired passive tones, and a clear, articulate single-coil.

Built with optimized-resistance coils and advanced audio op-amps for exceptional response and efficiency, MortalCoil is a powerful, versatile active upgrade. Introducing Seymour Duncan’s MortalCoil: an active humbucker set with three voices engineered for precision, power, and musical clarity. Designed from the ground up for modern players who demand brutal articulation and authoritative low end, the new primary MC1 voice delivers an exceptionally tight, mix-ready modern metal sound that stays focused and controlled across complex riffs, palm mutes, and harmonics. Alongside it, MortalCoil brings additional voices drawn directly from Seymour Duncan’s legacy: a classic JB and Jazz–inspired voice, plus a powerful single-coil voice ready when versatility matters. Built on 50 years of pickup-voicing expertise, MortalCoil represents a fresh approach to what multiple-voiced active pickups can be. MortalCoil’s MC1 (Voice 1) delivers uncompromising tightness, note separation, and cutting presence for modern metal applications, maintaining clarity and balance without fizz or nasal midrange, even under extreme gain. Voice 2 unlocks authentic JB Bridge and Jazz Neck voicings, capturing the proven character and feel players have trusted for decades. Voice 3 offers a strong, articulate single-coil voice with enough output and definition to hold its own in modern rigs, making it ideal for cleans, edge-of-breakup tones, and layered production. At the core of MortalCoil are precision-wound high-density copper coils with optimized resistance, providing faster transient response and stronger pick attack than competing designs across all tunings. Our all-new preamp utilizes advanced audio op-amps that contribute gain, rich harmonic detail, and dynamic feel with extremely low distortion, while the efficient circuit design supports superior battery life for reliable performance on stage and in the studio. The result is crushing attack and surgical control under modern metal gain. Whether you’re tracking or performing live, MortalCoil allows one guitar to move effortlessly from pristine cleans to aggressive high-gain tones. Experience what happens when 50 years of pickup expertise meets modern active technology. MortalCoil installs easily as a drop-in upgrade for many existing active setups and includes all required pots and wiring. Available now in 6-string and 7-string configurations.
