Here we have a very well preserved Yamaha SX-900A – “The Devils Head” , 1977, first issue in Tobacco Sunburst finish. This guitar belongs to the now discontinued Yamaha SX series, also known as the “Devil Heads” series, due to its distinct angular features. The black version would also qualify as Batman’s Axe. These guitars are quite rare, and although they were mad primarily for the domestic market, even in Japan they are rare. Initial production started in 1974 alongside the Yamaha SG range; The Yamaha SX-900A is the top of the range of the series and like its sibling the SX-800A, sports 2 Hum-bucker high output pick ups that can be engaged with a 3-way pick up selector switch. The tonal variety and range of the guitar is immense, and varies from soulful and clear, to a powerful growl. The A models were kitted out with hum-buckers and the B models had 3 single coils pickups. The construction materials varied between the A and B versions. The A version was made out of Maple and Mahogany for the body and the neck was built from mahogany with an ebony board.
There are some indications this type was in use by Tommy Bolin with Deep Purple and earlier by Rory Gallagher… For photo’s see: http://www.rorygallagher.com/#/archives/guitars/sx800b. Lives in original hard case
