The Yamaha FS400 is designed for players who prefer a smaller, more comfortable body without sacrificing tone or projection. Featuring a solid spruce top paired with mahogany back and sides, this concert-size acoustic delivers a clear, warm, and balanced sound that shines in both strumming and fingerstyle playing.
Its slim, easy-to-play neck and smooth fretboard make it ideal for beginners, smaller players, and anyone who values comfort during long practice sessions. Built with Yamaha’s renowned attention to detail, the FS400 offers reliable performance, beautiful tone, and classic style — all at a great value.
