For players preferring a Nylon Stringed Guitar.. with a USB input! he Heartsong Series is another Luna innovation, sparked by asking players what would facilitate their creative process. What was heard is that flashes of creativity do not always happen at opportune times and inspiration is sometimes lost. Luna got to work with Fishman to develop a plug and play system with a USB output that allows a player to capture their creativity on the fly. This Folk-Body Guitar features a distinctive treble/bass clef inlaid mahogany and lacewood rosette, and a pearloid fingerboard design inspired by musical notation and it sounds even better than it looks. For you Vegans out there that have been requesting a guitar without mother of pearl or abalone, Luna can recommend this guitar as having no animal byproducts. Case sold separately.
