The Jackson Pro Plus Series Signature Sleep Token IV Monarkh SC in Transparent Black Burst is an instrument built for atmosphere, depth, and commanding presence. Its Monarkh body is crafted from mahogany with a gloss finish, featuring a maple cap with quilt maple veneer and elegant 3-ply W/B/W binding. The dark Transparent Black Burst finish highlights the natural character of the quilted maple, while the Jackson 3x3 headstock, black hardware, black pickup covers, dome-style control knobs, and locking strap buttons complete its distinctive aesthetic.

The three-piece caramelized maple neck features a satin finish, set-neck construction, and graphite reinforcement for stability and resonance. Its pale moon ebony fingerboard has a 12 to 16 inch compound radius, 22 jumbo stainless steel frets, pearloid teardrop inlays, and Luminlay side dots for visibility in darker settings. A dual-action truss rod with wheel allows for precise adjustment, while the phenolic nut measures 1.6875 inches, or 42.86 mm, in width. With its 30 inch, or 762 mm, scale length, the instrument is purpose-built for deep, extended-range playing while maintaining clarity and control.

The tonal foundation comes from a Fishman Fluence Open Core HH pickup configuration, featuring the COC-BB1 bridge pickup and COC-NB1 neck pickup. The three-position toggle selects bridge, bridge and neck, or neck pickup combinations, while the volume control incorporates push-pull voice activation for expanded tonal versatility. An EverTune F6 bridge works alongside Jackson sealed die-cast locking tuning machines to provide dependable tuning stability, while D'Addario EXL156 Bass VI nickel-plated steel strings in .024 to .084 gauges complement the extended scale and powerful low-register character.

Weighing 9 lbs 6 oz and supplied with a gig bag, the Jackson Pro Plus Series Signature Sleep Token IV Monarkh SC brings together premium construction, distinctive aesthetics, and a voice designed to descend into darker territory. Every element, from its caramelized maple neck and pale moon ebony fingerboard to its Fishman Fluence electronics and EverTune bridge, has been chosen with purpose. It is an instrument that feels equally at home beneath the stage lights or in the quiet before the first note, where weight, tension, and atmosphere become one.
