  • Patent number: 4018124
    Abstract: An automatic guitar tuner for a standard six string electric guitar which includes a pick-up, a master crystal oscillator, and a tone generator for each string of the guitar. The pick-up feeds a frequency comparator for each string of the guitar and each frequency comparator is fed by a separate tone generator. A light emitting diode is positioned under each of the strings of the guitar and is connected between the frequency comparator and a source of electricity, either battery or transformer. When the frequency of the individual tone generator and the frequency of the string match, the frequency comparator will complete a circuit through the light emitting diode so that the light emitting diode indicates that the individual string is properly tuned. When the string is out of tune it is adjusted in the normal fashion until the light emitting diode associated therewith is energized.
