The Ever-Evolving Japan-Made Bacchus Flagship Models [Deviser One Day 2026]

There are about two weeks left until the One Day Guitar Show 2026. In today’s article, we’ll be introducing “Handmade Series” and “Unique Series” models from Bacchus’s lineup of Japanese-made guitars. Ahead of the event, we’ll take a look at the craftsmanship behind each limited-edition model.

The Bacchus brand’s flagship product

Among Divider’s brands, “Bacchus Handmade Guitars” has built a long history by catering to a wide range of players, from high-end to entry-level. The “WOODLINE” and “DUKE” models have been the cornerstones of this brand, which has a history spanning more than 30 years, since its very beginnings.

Since its launch, it has been a key part of Bacchus’s top-of-the-line “Handmade Series” lineup. Their legacy has expanded to include models manufactured overseas; for example, the WOODLINE series has evolved into a broad lineup bearing the “WL” designation, while the DUKE series has branched out into a variety of derivative models. To this day, these models continue to enjoy the support of many players.

In addition, alongside our overseas-produced models, we have released numerous domestically produced models to date. By incorporating finishes that highlight the natural beauty of wood and limited-edition designs available only for a specific year, we have created many special models, each with its own unique specifications and story.

And at this year’s “Deviser One Day Guitar Show”, we’ll be unveiling a model that has evolved even further.

WOODLINE Opens New Doors with the Handmade Series

At this year’s “One Day Guitar Show”, we will be unveiling products featuring new specifications and designs, including a new model, the first in the WOODLINE series to incorporate a German curve.

The first WOODLINE model to feature a German curve

A “German curve” refers to the cutouts along the outer perimeter of the body; it is characterized by a three-dimensional finish that sets it apart from a flat top. To create a line that accentuates the body’s presence, we explored multiple patterns during the line-drawing stage and refined the design by testing the texture and feel on actual samples.

Currently in the painting process, this model exudes a somewhat bizarre presence thanks to the unique shading created by the German curve. Another noteworthy feature is the pickup cutout. As you can see from the side view, it appears to feature pickups that are wider than those typically found on JB-type guitars. The body is crafted from mahogany, which makes one wonder what the sound character will be like once it’s finished.

Now that the parts are being assembled, what kind of sound and appearance will this instrument ultimately have? As this model gradually begins to take shape, anticipation is building for its full reveal.

WOODLINE with a semi-hollow body made of Japanese red pine

Production is also underway on the WOODLINE semi-hollow model featuring an F-hole. This model uses Japanese red pine for the body, and combined with its lightweight construction, it is designed to let you fully appreciate the unique character of Japanese red pine.

Since launching the “JRP (Japan Red Pine) Guitars” project in 2017, which utilizes wood damaged by the red pine weevil, Deviser has been actively crafting guitars from local red pine. While we have used Japanese red pine in guitar production on numerous occasions, this marks the first time it has been incorporated into the WOODLINE series. Thanks to the expertise we’ve gained from our previous guitar-making experience, we look forward to the exceptional craftsmanship that the Aska Workshop will deliver.

Furthermore, this model incorporates a design inspired by the Japanese red pine trees planted at the Deviser Technical Center. The inspiration came from the Warbling white-eyes that were visiting these red pines around May and June of this year.

A distinctive call echoes across the company grounds.

The Warbling white-eye is a bird found throughout Japan, from Hokkaido to Kyushu, and is characterized by its distinctive appearance, with bright yellow feathers on parts of its plumage.

We’ve captured this striking scene, featuring Japanese red pine trees and warbling white-eyes, in the inlay work on the fingerboard. The Japanese white-eyes are meticulously depicted, looking as if they might alight on the pine branches at any moment, resulting in a design that evokes the warmth of nature.

It has been confirmed that the annual WOODLINE “Winter Sakura” model will also be on display.

We will also be exhibiting a “Winter Sakura” model, which has become a tradition at recent One Day Guitar Shows. “Winter Sakura” is a limited-edition model based on the theme of “Winter × Sakura,” featuring an F-hole inspired by cherry blossoms and winter motifs, and cherry blossom inlays on the fingerboard. This year’s Winter Sakura features an adorable rabbit-themed design, which can be seen on the body as it awaits the final coat of finish.

When I went to observe the fingerboard production process, I saw that two adorable rabbits had been brought to life alongside snowflake and cherry blossom designs.

With these little guys always by your side, on both the fretboard and the body, you might find yourself wanting to give them names. The full lineup will be revealed on the day of the One Day Guitar Show 2026.

The “DUKE” model, part of the newly launched “UNIQUE” lineup

Launched in 2025, “UNIQUE” is a new series of domestically produced Bacchus models. The “Made in Japan DUKE”, which had been out of production for a long time, has made its long-awaited comeback as the “New DUKE” under a new production system, while retaining the fundamental structure and design philosophy cultivated over many years.

One of the core concepts of the UNIQUE Series is the Chinese zodiac. Beginning with last year’s Year of the Snake model, the series incorporates designs inspired by the Chinese zodiac sign of the year of manufacture, resulting in timepieces that embody the unique character of each year.

The Year of the Horse model, which was unveiled at the “Deviser Special Showcase 2026” held in May, will make a fresh appearance at this year’s One Day Guitar Show, showcasing a new look and a different charm. We’ll share more details soon, so please stay tuned for updates.


Ahead of the launch of the special website for the One Day Guitar Show on November 22, we’re giving you an exclusive sneak peek at the latest information on the models each brand will be showcasing on our countdown page. We’ll be bringing you the inside scoop on the manufacturing process and a look inside the factories first!
