Japan Tune-up: the Bacchus spirit, a WL5 built for the stage

This JT WL5-SPM-AC RSM/M NAS belongs to Bacchus' Japan Tune-up series. In this range, the goal is clear: to offer a bass with a carefully crafted playability level, with wood and electronics choices designed to be immediately effective in rehearsals as well as concerts. Made in Indonesia, it stands out by its very "musician" approach: neck comfort, useful adjustments, and natural finishes that highlight the material.

Who is this WL5-SPM-AC for?

With its 5 strings and active preamp, this Bacchus targets the bassist who wants an instrument capable of holding a dense mix and adapting quickly to various contexts. It suits intermediate to advanced levels very well (and remains accessible if you are starting on 5 strings), especially for funk, pop, modern rock, gospel, fusion, and all styles where a clean and usable low B string makes the difference. The Preamp On/Off switch is also a real plus to keep a simple and effective sound or, on the contrary, to refine your place in the spectrum depending on the venue and amp.

Sound character: 5-string JB + preamp, between attack and control

The WL5-SPM-AC RSM/M relies on an Original JB Set (two Jazz Bass-type pickups): it offers precise attack, clear mids, and excellent definition for fingerstyle and pick playing. The JB configuration allows balancing between the neck pickup (rounder, fuller) and the bridge pickup (more articulated, punchier) to switch from a wide groove to a more "snappy" sound.

Its real asset is the active electronics around the Bacchus BBP2 preamp: the Bass and Treble EQ controls immediately adjust the low end (foundation, depth) and the high end (attack, brightness) without losing volume or presence. And when you want a more direct behavior, the Preamp On/Off Switch brings you back to a rawer response, ideal for "plug and play" sounds or to maintain a very natural dynamic.

In terms of feel, the roasted maple neck provides a dry and fast sensation under the fingers, with a clear attack. The hardware also contributes to stability: the JB Bridge with brass saddles promotes a well-set note, solid sustain, and reliable intonation, particularly appreciated on a 5-string.

Recommended compatible accessories

To get the best out of this bass from day one, you can plan for a good quality 6.35 mm jack instrument cable (essential in studio and on stage), as well as a D'Addario XL-165-5 string set (originally mounted) to maintain the same balance of tension and response. A tuner and a bass stand will also fit without compatibility issues.
