Eight-string guitar

Eight-string (8) guitar
An eight-string guitar is a guitar with eight strings instead of the commonly used six strings. Such guitars are not as common as the six string variety, but are used by classical, jazz, and metal guitarists to expand the range of their instrument by adding two strings.
There are several variants of this instrument, one probably originating from Russia along with the seven string guitar variant in the 19th century. The eight string guitar has recently begun to gain popularity, notably among jazz artists such as Charlie Hunter, The Special Purpose, Terje Rypdal and Richard Scott, and metal artists such as Meshuggah, Stations, and After The Burial. There are steadily increasing numbers of manufacturers offering eight string guitars, and a production eight string was released in 2007 by Ibanez. Some of the main manufacturing companies of 8 and even 9 string guitars are Novax Guitars established by Ralph Novak and ConklinGuitars. Recently ESP Guitars has also begun to make production line eight string guitars as well.

The 8 string electric guitars are used by Meshuggah, Rusty Cooley, Scale the Summit, Dino Cazares of Asesino, Fear Factory, Divine Heresy, Deftones, Stations, After the Burial, High on Fire,Trapt and other metal artists are most often tuned in regular 4ths, with two extra basses (Low to High) F#,B,E,A,D,G,B,E.
