Jackson and Charvel have announced their first signature collaboration with Sleep Token, unveiling two new instruments built to the exact specs of the band’s guitarist, IV, and bassist, III – the Jackson Pro Plus Series Signature Sleep Token IV Monarkh SC and Charvel Sleep Token III Signature Pro-Mod San Dimas Bass V.
IV’s instrument, the Jackson Pro Plus Series Signature Sleep Token IV Monarkh SC ($2,199.99), is built around his signature whole-octave-down tuning. A 30″ scale length and precision-engineered EverTune 6 bridge with custom saddles keep tuning rock solid in that extended low range, while a bound Mahogany body with quilt Maple veneer and a three-piece caramelized Maple set-neck provide the tonal foundation.
A compound radius pale moon Ebony fingerboard with 22 stainless steel frets keeps things playable from crushing riffs to expansive chord work, and direct-mount Fishman Fluence Open Core Classic humbuckers deliver clarity across both clean and heavily saturated tones. Pearloid teardrop inlays, Luminlay side dots, and a matching headstock round out the look, with a foam core case included.
III’s bass, the Charvel Sleep Token III Signature Pro-Mod San Dimas Bass V ($1,599.99), is a five-string built around a resonant poplar body and a caramelized Maple neck with a progressive 12″-16″ compound radius and jumbo frets. Its multi-scale, fanned-fret design spans 34.4″ to 35.5″, optimizing tension across all five strings for cleaner intonation and the percussive attack central to III’s playing.
Custom red Fishman Fluence soap bar pickups offer three voicings via a mini toggle, paired with an onboard 2-band EQ and blend knob for detailed tonal control. Hipshot Ultra Lite tuners, locking strap pins, and a reverse licensed Stratocaster headstock complete the build.
Both instruments are available now here.
