Abstract: A stringed instrument with an on-board tuner which detects vibrations of the strings and determines and displays the identity of the string which is being played and the deviation of the string's pitch relative to an in-tune reference pitch. The tuner display is situated such that it is not readily visible to casual observers, such as an audience, yet is oriented such that the musician can easily view the tuner display from a normal playing position. In the case of an electric stringed instrument, the display is inlaid in the top surface of the neck of the instrument near the instrument's body. In the case of an acoustic stringed instrument, the tuner is mounted inside the body of the instrument and is visible through the sound hole. The instrument is provided with a strap assembly which attaches to a balanced pivot point on the instrument and provides a single connection which serves as both an electrical connection to the amplifier and a mechanical connection to the strap assembly.

Abstract: A strap mounting assembly mounts to the rear face of a guitar body having an electrical pickup therein at a balance point permitting rotation of the guitar body about a horizontal axis at that balance point. The assembly includes a flat face plate having a tapped hole therein, a ring connector concentrically mounted about the tapped hole and insulated from the metal base plate. The flat base plate is screwed to the rear face of the guitar body with the ring connector facing outwardly. An elongated electrically insulated material molded arm has outboard and inboard ends, each including a hole therein along a longitudinal center line at right angles to the center line. A retainer button projects through one end of the strap, and is rotatably mounted within the first hole via a metal sleeve and is threaded into the base plate tapped hole.
