Another important aspect of this guitar that is different from the classic model is the elevated fingerboard in which the strings intersect the top contact at an angle, as they do with the soundboard of a harp; a modulation that has been successfully described and applied by the respected Thomas Humphrey, luthier. The increased angle between strings and top results in an increased tractive force to the soundboard and body making it sound louder and brighter (comparable to a harp). In the normal situation the fingerboard meets the body at the 12th fret. In the Butterfly model the fuse between body and neck is made at the 14th fret with a longer playable fingerboard as a result.

Therefore, the Butterfly classical guitar is a good choice for a professional or an experienced guitar player who likes to perform their guitar playing skills for family, friends or public.
