The Heartsong Series is another Luna innovation, sparked by asking players what would facilitate their creative process. What we 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. In addition to the USB feature, the Fishman Isys+ pre-amp with built-in tuner ,1/4" and USB outputs faithfully recreates the amplified sound of this impressive 6-string. This Parlor-sized guitar features a distinctive treble/bass clef inlaid mahogany and lacewood rosette, and a pearloid fingerboard design inspired by musical notation. This is a great guitar for people desiring the flexibility of a USB output and comfortable, great sounding Parlor guitar.
