Fred Frith has used a number of different guitars, including homemade instruments, over the years, depending on the type of music he is playing. For the more structured and refined music he has often used a Gibson ES-345, for example on his solo album, "Gravity". For the heavier "rock" sound, as in Massacre, he has used an old 1961 solid body Burns guitar, created by the British craftsman Jim Burns. On his landmark "Guitar Solos" album, Frith used a modified 1936 Gibson K-11 guitar (q.v. for details).
