Low End from Behind the Mask
The Charvel Sleep Token III Signature Pro-Mod San Dimas Bass V is the signature 5-string of the masked bassist known only as III, built to match the mystery and range of one of modern music’s most enigmatic bands. Sleep Token trades names and faces for Roman numerals and masks, and their music refuses to sit still, constantly shifting across genres, from alternative rock and progressive metal to pop and R&B. III anchors it all, and this signature bass is built to cover the same ground. Two Fishman Fluence Bass Soapbar multi-voice pickups deliver a deep arsenal of tones via an active 2-band EQ, while a 34.4–35.5-inch multi-scale design keeps the low B tight and defined. Additionally, a caramelized maple neck and a 12–16-inch compound-radius fingerboard make fast, expressive playing effortless across all 24 frets. Finished in gloss black and marked with III’s own iconography, this San Dimas Bass V wears the band’s ritualistic aesthetic as unmistakably as it delivers their sound.

The bassist behind the mask
Sleep Token has become one of the biggest acts in the world without ever showing a face. As the British band’s bassist, III channels everything into the music and mythology rather than personal fame. He provides the low-end foundation beneath a sound that swings from crushing heaviness to atmospheric, genre-blurring calm. This signature San Dimas turns that identity into an instrument. Its black finish and matching hardware complement the band’s dark stage aesthetic. The fretboard carries an “iii” inlay near the neck joint and an oversized question-mark inlay across the middle, echoing the band’s cryptic symbolism, while red pickup covers and a reverse headstock complete a look as deliberate and mysterious as III’s masked onstage presence.


Built to keep up with III
III’s parts demand a bass that can keep up, and the San Dimas platform, under the signature styling, is built for exactly that. A multi-scale design spanning 34.4 to 35.5 inches tightens and clarifies the low B while keeping the higher strings comfortable. A 1-piece caramelized maple neck with graphite reinforcement stays fast and stable under heavy playing, and its 12–16-inch compound-radius fingerboard runs rounder at the nut and flatter toward the heel, with rolled edges keeping all 24 frets smooth and comfortable. Rounded out with a contoured poplar body, a heel-mounted truss-rod adjustment wheel, Hipshot Ultralite tuners, and Luminlay side dots, the Sleep Token III Signature Pro-Mod San Dimas Bass V is a gig-ready instrument. Sweetwater’s bassists reach for it as much for its proven San Dimas performance as for its unmistakable style.
A voice for every extreme
Sleep Token’s music lives in extremes, and III’s bass has to speak to them all. Two Fishman Fluence Bass Soapbar pickups make that possible, using Fishman’s multi-voice Fluence Core technology to pack several distinct voices into a single instrument. A 3-way toggle switches between them, spanning a classic, fat, round passive tone, a full-frequency active voice with dynamics to spare, and a mid-contoured setting scooped for funk-ready, hi-fi territory. A single-coil mode adds a J Bass–style window for even more range, and because these are Fluence pickups, every voice stays free of the hum and noise that plague traditional wire-wound designs. A Blend control and active Bass and Treble EQ fine-tune it all, giving III — and you — an arsenal deep enough to cover the whole of Sleep Token’s sound.
