Authentic entry model using popular materials has been remodeled to a beautiful gloss finish in recent years. The dreadnought type SD304 using Sitka spruce & mahogany materials, which is becoming rare in recent years, is an acoustic guitar with a clear and warm sound. The nut is made of NUBONE and is transmitted to the guitar body without disturbing the string vibration, realizing a sound with a sense of openness. The body finish is an entry-level model with a glossy finish and a luxurious appearance, but it is a "genuine-oriented" acoustic guitar.
