ABSTRACT:
A digital guitar processing circuit includes a guitar converter circuit and a guitar formatting circuit. The guitar converter circuit receives one or more analog string signals representative of the string vibrations of a guitar and generates one or more digital string signals based upon the analog string signals. The guitar formatting circuit formats the digital string signals to be compatible with a digital communication protocol, and outputs the formatted digital string signals.
