Japan Tune-up: a "ready-to-play" approach in the Bacchus world

This Bacchus JT WL5-QM-AC RSM/M belongs to the Japan Tune-up series, a range designed to offer a refined playing feel and serious equipment level while maintaining the "musician's instrument" spirit: efficient, reliable, and performance-oriented. With its Amber Burst aesthetic, figured top, and modern wood choices, it positions itself as a 5-string bass tailored for stage and studio, where attack precision, stability, and sound control make all the difference.

Who is this 5-string Bacchus for?

With its 5 strings and switchable active electronics, this model is particularly aimed at intermediate to advanced bassists seeking an extension into the low register (B string) without sacrificing definition. It is also suitable for a confident beginner wanting to start directly on a 5-string to play contemporary repertoires.

Its playground is broad: funk and neo-soul (snappy and dynamic), pop and variety (clear presence in the mix), gospel and modern music (deep and controlled low end), as well as rock and metal when you want sharp attacks and solid lows. The TYPE S format and immediate access to controls make it an intuitive bass to switch contexts without struggling with your sound.

Precise tone, from vintage to modern, with real control

The sonic personality of this Bacchus revolves around a balance between attack, definition, and body. The quilted maple top generally provides a lively response and a clear attack feel, ideal for highlighting right-hand playing details. The walnut body is appreciated for its present mids and depth: a good compromise between warmth and precision, very effective when you want a bass that "speaks" in a dense mix.

The roasted maple neck and fingerboard reinforce this impression of immediate response: the feel is fast, the note starts clearly and remains readable across the entire neck, a real plus on a 5-string. The open-pore finish (satin) also contributes to a more organic hand feel and natural resonance, without the "thick varnish" effect.

On the electronics side, the Original JB Set pickups (Jazz Bass type) provide a formidable base to cover very varied registers: articulate grain, good note separation, and clear attacks. The Bacchus BBP2 preamp with 2-band EQ (Bass / Treble) allows you to quickly dial in a more massive low end for modern styles or, conversely, brighten the upper spectrum for slap and percussive lines. Finally, the Preamp On/Off switch offers valuable flexibility: you can stay in active mode for fine sculpting, then switch to bypass mode for a more direct and simpler sound depending on the amp, venue, or song.

Recommended compatible accessories

To maintain exactly the original feel and tension, you can plan to use a D'Addario XL-165-5 string set (the factory-installed model) as replacements when changing strings.
