The Bacchus WJB-1MS-DX-AC RSM/M is a forward-thinking, multi-scale bass that blends vintage warmth with modern ergonomics. Built for players who demand superior string tension balance, extended range clarity, and effortless playability, this Japanese-designed instrument features a lightweight Poplar body, a fully roasted Maple neck and fingerboard, and a powerful onboard active preamp. Whether you're a progressive metal virtuoso or a studio session player, the WJB series delivers articulate tone across every fret. Why Fanned Frets? (Multi-Scale Design) Unlike traditional parallel frets, the WJB-1MS-DX uses a fanned fret (multi-scale) system: Low strings (35” scale – 889mm) : Enhanced tension and definition – no more floppy B or E strings, even in drop tunings. High strings (34” scale – 864mm) : Comfortable, slinky feel for bends and fast runs. Result : Optimized intonation, reduced inharmonicity, and a natural hand position that reduces fatigue. Premium Roasted Maple Neck & Fingerboard The entire neck and fingerboard are crafted from roasted Maple – a heat-treatment process that removes moisture and oils. Benefits include: Exceptional stability against temperature and humidity changes A rich, resonant midrange snap with vintage-style attack Smooth, dry playing feel (no sticky finish) Distinct charcoal-amber aesthetic that pairs beautifully with the AC (Antique Cognac) finish Stainless Steel Frets & Bone Nut Stainless Steel frets : Virtually wear-resistant, glassy string bends, and long-lasting playability. Bone nut : Superior harmonic transfer and tuning stability compared to plastic. Electronics & Controls – Total Tonal Freedom The Original JB-Type pickup captures classic jazz bass growl, but the real magic lies in the active preamp: Control Function 1x Volume Master level 1 x Balancer Blend between neck and bridge pickups Treble (active)Boost/cut high frequencies – add snap or roll off harshness Bass (active)Boost/cut low end – from tight punch to deep subsonic rumble Hardware & Build Details Bridge : Single-string type (individual saddles) – perfect for multi‑scale intonation adjustment and isolated string vibration. Machineheads : Open gear type – vintage look, precise tuning, reduced weight. Fingerboard Radius : 305R (approx. 12”) – comfortable for both chord work and low-action soloing. Nut Width : 38.0mm – familiar Jazz Bass spacing, ideal for fingerstyle or pick playing. Finish : Durable Polyurethane/Polyester (AC – Antique Cognac / Rusted Metallic? please check dealer notes).
