Bacchus JT WL4-QM RSM/M CHGS

Japan Tune-up: Bacchus DNA Between "JB" Tradition and Refined Finishes

This Bacchus belongs to the Japan Tune-up series, a line designed to offer the brand's signature aesthetics and playability, focusing on precise setups and overall coherence. The WL4-QM RSM/M model features a TYPE S format inspired by classic "JB" basses: dual single-coil pickups, familiar ergonomics, and effective balance for both standing and seated playing.

In this CHGS variant, the quilted maple top and satin finish add a distinct personality while remaining understated enough to fit any backline. Made in Indonesia, it aims for an excellent balance between performance level, reliability, and everyday playing enjoyment.

A 4-String Bass Designed for Progression... and Band Playing

The Bacchus JT WL4-QM RSM/M CHGS is ideally suited for demanding beginners and intermediate bassists seeking a serious, inspiring instrument capable of handling rehearsals and live gigs. Its long scale and intuitive controls (two volumes, one tone) make it easy to handle: focus is on rhythmic placement and attack, not complex settings.

Style-wise, its "JB" configuration excels in funk, rock, pop, indie, blues, and modern jazz. By blending the two pickups, you can shift from a warm, enveloping sound to a more punchy, articulated tone. The Turbo Switch adds an extra option to increase density and presence when the song calls for it.

Sound: "JB" Clarity, Precise Attack, and "Turbo" Option for More Body

Equipped with an Original JB Set, this bass delivers the typical character of a dual "JB"-style pickup configuration: definition in the mids, clear attack, and excellent note clarity, especially appreciated in fingerstyle and slap playing. The bridge pickup adds bite and precision for lines that need to cut through the mix, while the neck pickup reinforces low mids for a rounder, more "old school" tone.

The electronics remain intentionally straightforward with 2 volumes and 1 tone: a perfect setup for quickly shaping your sound. The pull-up tone control activates the Turbo Switch: a mode designed to provide extra energy, useful for thickening a line, boosting impact on a chorus, or simply achieving a more pronounced output feel without changing basses.

The craftsmanship also contributes to the sonic experience. The torrefied maple neck promotes a lively and consistent response, often perceived as a "drier" and more precise feel. The natyoh body contributes to overall comfort and a balanced tonal foundation. Finally, the quilted maple top adds extra presence and perceived brightness, while marking the visual identity of this model.

Recommended Compatible Accessories

To ensure compatibility, you can opt for a D'Addario XL-165 string set (the original factory-installed reference) to maintain the same feel and tension, as well as a quality 6.35 mm instrument jack cable to minimize noise interference. A microfiber cloth is also recommended to care for the satin finish and keep the top immaculate after each session.
