Abstract
Abstract Described is a stringed instrument construction, particularly a guitar construction, including a seamless, hollow, one piece body portion or sound box molded from a synthetic material. The body can be molded by conventional spin or roto casting techniques. The body portion or sound box is acoustic and can therefore be used for either an electric type instrument or a conventional manual or acoustic type instrument. A neck construction is also described comprising a metal and hardwood laminate which does not allow any significant deflection due to string load.
