Bacchus JT WL5-SPM-AC RSM/M BLKS-B

Japan Tune-up: a WL5 designed for playability and setup

With the "Japan Tune-up" series, Bacchus focuses on the playing experience: a comfortable, responsive instrument ready to follow a bassist daily, from studio to stage. This WL5-SPM-AC RSM/M positions itself as a modern and accessible 5-string, made in Indonesia, with an approach centered on playability, consistency, and electronics adaptable to various musical contexts.

For which bassists and styles?

Thanks to its 5-string configuration and activatable preamp, this Bacchus is particularly aimed at intermediate bassists who want an all-around bass, but it is also suitable for a motivated beginner seeking an evolving instrument, as well as an experienced musician wanting a reliable 5-string for rehearsals, recording, and live playing. The low B string opens the door to repertoires requiring deep lows: gospel, modern pop, metal, fusion, R&B, while remaining equally relevant in funk and rock when you want to anchor the mix without forcing.

Sound Character: JB pickups and preamp to shape the mix

The WL5-SPM-AC RSM/M features an Original JB Set (Jazz Bass type), appreciated for its definition and ability to switch from a round, warm tone to a more snappy attack depending on your right hand. This "JB" base is ideal for articulating ghost notes, highlighting fingerstyle nuances, and achieving a clear slap sound. The Bacchus BBP2 preamp, activatable via the Preamp On/Off Switch, adds headroom and EQ to quickly adjust your place in the band: more present lows to thicken the bottom end, brighter highs for increased attack and precision. On the lutherie side, the combination of a Natyoh body and a roasted maple neck promotes a fast response, solid sustain, and a controlled feel, while the open-pore finish preserves a more "organic" touch, very pleasant during long sessions.

Recommended Compatible Accessories

To maintain exactly the same playing feel and balance, plan for a D'Addario XL-165-5 string set (same reference as the original setup). For amp use, a good quality 6.35 mm jack cable remains the safest and most universal accessory for an electric bass, and since the
