Some years ago my wife, who is a musician, asked me to build her an acoustic guitar. This introduced a new dimension into woodworking for me: the exploration of sound through the resonance of the different woods. My first guitar (pictured below) was built with a mahogany back and sides and an old growth spruce front with an ebony fingerboard.
I am currently building a classical guitar, a copy of a 1937 Herman Hauser, Andes Segovia's favourite guitar. I am using red cedar for the front, and pau amarillo for the back and sides. This guitar has amazing provenance already - the cedar came from a totem pole that was being carved for Dockside Green in Victoria.
