ABSTRACT:
An automatic tuning device for guitars and string instruments in general having a string tensioning mechanism adapted to vary the tension of the strings from the tail piece in response to the differences detected between the reference signals and the string signal produced. A reversible D.C. motor provides the rotational motion that is translated into a proportional linear motion that is used to either pull or release each one of the strings.
