Deviser Co., Ltd.

In Matsumoto, Deviser works across product planning and the manufacture of stringed instruments. The company was established in 1991 as an independent sales division of the Headway factory and has since developed and distributed guitars, basses, and ukuleles under several house brands. Its catalog brings together acoustic and electric instruments, with lines ranging from everyday models to more elaborate series.

Headway focuses on acoustic guitars and ukuleles; Bacchus covers electric guitars and basses; Momose Custom Craft Guitars and SeventySeven offer other approaches to the electric guitar. The family also includes STR and Deviser Special Specification, along with accessories and parts. Deviser plans and develops products and combines domestic and international manufacturing locations to serve different specifications and price ranges.

The company highlights the use of regional Japanese woods in some lines, alongside materials and finishes specific to each series. That focus appears in collections exploring different woods and techniques, as well as models created with artists or for specialist retailers. Its website organizes products by instrument, brand, artist, and new releases, and includes news, demonstration videos, and events where it presents models and collaborations.

Deviser is not only a direct-to-consumer retailer: its work includes wholesale sales, promotion of its brands, and exports to international distributors. The company profile lists a network of about 400 music stores in Japan and roughly 30 overseas distributors. A retailer search on its website lets customers look by prefecture or country; instruments are purchased through those dealers.

The company also directs owners to warranty, first-owner registration, and maintenance information. Its group includes Aska Ltd., established in 2004 and focused on designing, developing, and manufacturing stringed instruments; Deviser lists a nearby Aska address at 7071-3 Sasaga, Matsumoto. Deviser’s own office is at 7072-6 Sasaga, Matsumoto, Nagano 399-0033. For musicians comparing Japanese brands, Deviser’s profile clarifies who develops the product lines and how they reach retailers.
