Bacchus WJB5-1MS-DX-AC RSM/M Electric Bass 5 String Roasted Maple Fanned Frets Active Black

The Bacchus WJB5-1MS-DX-AC RSM/M takes the acclaimed multi‑scale design and expands it to five strings. Built for bassists who demand a tight, articulate low B without floppiness, this instrument combines a lightweight Poplar body with an all‑roasted Maple neck and fingerboard, stainless steel frets, and a powerful active preamp. Finished in sleek Black, the WJB5‑DX delivers professional studio and stage performance at an exceptional value.

Why Fanned Frets on a 5‑String?

The multi‑scale (fanned fret) system solves the classic 5‑string compromise:

• Low B (5th string) – 35” scale (889mm) : Maximum tension and definition – no mud, no wobble. Drop tunings stay punchy.

• High G (1st string) – 34” scale (864mm) : Comfortable, familiar feel for fast fills, chords, and bends.

• Graduated frets : Naturally align with your hand’s ergonomics, reducing wrist strain during long sets.

Fully Roasted Maple Neck & Fingerboard

Every piece of Maple in the neck and fingerboard has been heat‑treated (roasted). Advantages include:

• Ultimate stability – Resists warping from humidity and temperature changes.

• Rich, dry resonance – Enhanced midrange snap and sustain, without excessive overtones.

• Smooth playing feel – No sticky gloss; a fast, satin‑like surface.

• Beautiful dark caramel hue – Complements the Black body for a stealthy, high‑contrast look.

Stainless Steel Frets & Bone Nut

• Stainless Steel frets : Indestructible under roundwound strings; polished, glassy bends; no fret wear worries.

• Bone nut (46.0mm width): Superior energy transfer and open string clarity, perfectly spaced for 5‑string feel.

Active Electronics – Complete Tonal Control

The Original JB‑Type pickup provides that classic jazz bass growl and punch. Combined with the Original Active Preamp (Treble/Bass), you get active power with intuitive control:

Control Function

Volume Master level

Balancer Blend neck & bridge pickups

Treble (active)±Boost/Cut – add sparkle or tame harshness

Bass (active)±Boost/Cut – from tight thump to deep subwoofer rumble

Tip : The passive tone of the JB pickup is always available when the preamp is set flat – best of both worlds.

Hardware & Build Details

• Bridge : Single‑String Type – independent saddles allow perfect intonation for each scale length. Excellent string‑to‑string isolation.

• Machineheads : Open Gear Type – vintage aesthetic, precise tuning, reduced headstock weight.

• Fingerboard Radius : 400R (approx. 15.75”) – flatter than traditional basses, ideal for low action, fast solos, and chordal playing.

• Nut Width : 46.0mm – comfortably wide for 5‑strings without feeling like a baseball bat.

• Finish : Durable Polyurethane / Polyester – Black.

• Strings : .045–.130 roundwound (ready to play).

• 5‑string converts – Tired of floppy low B? The 35” scale changes everything.

• Progressive & metal bassists – Clear note separation even with heavy distortion.

• Session players – Active EQ lets you dial in any genre, from R&B to fusion.

• Touring musicians – Roasted Maple + stainless frets = minimal maintenance.

• Most affordable multi‑scale 5‑strings use standard Maple or cheaper woods. The WJB5‑DX gives you fully roasted Maple neck & board, stainless frets, and a bass/treble active preamp – features found on basses costing twice as much. Add the ergonomic fanned fret design and you have a serious tool for modern bass playing.
