Fender's Jackson and Charvel brands have unveiled signature instruments for the two masked SLEEP TOKEN members known as IV and III — and the specs make it very clear what problem each was built to solve.
The Jackson Pro Plus Series Signature SLEEP TOKEN IV Monarkh SC is a baritone in all but name. It runs a 30-inch scale, long enough to hold tension a whole octave below standard tuning, and mounts an EverTune 6 bridge with custom saddles to keep that tuning stable under the kind of playing that would put a conventional bridge out immediately.
The rest is high-end appointment work: a bound mahogany body with quilt maple veneer, a three-piece caramelized maple set-neck, a pale moon ebony fingerboard with 22 stainless steel frets over a compound radius, pearloid teardrop inlays, Luminlay side dots and a matching headstock. Pickups are direct-mount Fishman Fluence Open Core Classic humbuckers. It ships in a foam core case at $2,199.99 / £1,949 / €2,299 / AU$4,499 / ¥396,000.
The Charvel SLEEP TOKEN III Signature Pro-Mod San Dimas Bass V goes the other route — five strings and a multi-scale fanned-fret layout running 34.4 to 35.5 inches, which lengthens the low B without making the top strings unplayable. The body is poplar, the neck and fingerboard caramelized maple, with a progressive 12"–16" compound radius and jumbo frets.
Electronics are where it gets interesting: custom red Fishman Fluence soap bar pickups with three switchable voicings, a Fishman 2-band EQ for bass and treble, and a blend knob for mixing the pickups. Hardware includes Hipshot Ultra Lite open gear tuners, locking strap pins and a reverse licensed Stratocaster headstock. Price is $1,599.99 / £1,399 / €1,649 / AU$2,699 / ¥258,500.
Both instruments were designed by the players themselves — IV, the band's lead guitarist and backing vocalist, on the Jackson; III, the bassist, on the Charvel.
"SLEEP TOKEN's sonic and visual identity is distinctive, and these signature models shape that sound," said Justin Norvell, Chief Product Officer at Fender Guitars.
That is marketing language, but the underlying point holds. A band whose entire low-end architecture depends on a guitar tuned an octave down staying in tune, and a bass that can sit clean under piano and R&B passages before dropping into djent, has genuinely specific hardware requirements. These are those requirements, turned into products.
It is also a marker of scale. Signature models from Fender's metal-facing brands go to players with sales behind them, and a band still refusing to give out its members' names has now cleared that bar on the strength of the music alone — "The Summoning" long since platinum, and a fanbase that treats the anonymity as part of the deal rather than an obstacle to it.
