An electric stringed instrument, e.g. an electric guitar, featuring a body having a rectangular shaped, through-the-body cutout between the neck and bridge, and having a connector in a portion of the cutout. Pins on the connector are wired to electronic control components that are permanently fixed in the body. A rapidly interchangeable pickup assembly containing one or more pickups, in any combination of single and dual coils, fits into the cutout. Many and varied pickup assemblies, each with different characteristics of tone, strength, and frequency range emphasis can be interchangeably installed into the cutout. A connector on the pickup assembly mates with the body connector, thus accomplishing an electrical connection between the pickups in the assembly and the control electronics. The pickup assembly, having no control electronics on it, is light, compact, and easily maneuvered with one hand into and out of the cutout from the rear of the instrument. Once securely installed, the pickup assembly is in the optimum position to respond to string vibration. This vibration is converted into an electrical signal, sent and processed through the control electronics to an external unit for amplification.

A guitar-family-characteristic-sound selector switch (63) is incorporated into an electric guitar and used in conjunction with the normal guitar pickup selector switch (62) and the volume and tone controls. This guitar-family-characteristic-sound selector switch invokes different pickup (61) combinations and resistance / capacitance / inductance circuitry (68) in order to generate sounds characteristic of at least two other guitars in addition to the normal sound of the host guitar. In one implementation, the family selector switch is a single user controllable switch that makes the system is intuitive in that a single guitar-family-characteristic-sound selector switch is all that needs to be operated to put the guitar in the mode of sounding like one of three or more styles of guitars following such selection; the pickup selector, volume and tone controls are used in the usual manner.

Various kinds of members are located on the body of an electric guitar, and strings are supported by the members at predetermined positions along the longitudinal direction. The strings are adjusted by a fine-tuning element and a harmonic tuning element. A base plate is pivotally supported on the guitar body. Each of saddles is rotatably coupled to one of saddle holders, the position of which can be adjusted in the longitudinal direction of the strings, and corresponds to one of the strings. Each saddle contacts the corresponding string at a predetermined point. Each string holder, which is located in one of the saddles, holds the corresponding string at a part that is below the contact point of the string. The fine-tuning element fine-tunes each string by changing the rotational angle of the corresponding saddle without actually changing the contact point of the corresponding string. The harmonic tuning element adjusts the position of each saddle holder in the longitudinal direction of the strings. A manipulation portion, which is located on the harmonic tuning element, tunes the harmonic of each string at a position above the base plate while the string is held by the associated string holder.
