In a stringed instrument which generates sound reproduction output signals by way of a transducer which are amplified for sound reproduction, a fundamentally correct note frequency signal is generated and electromagnetically broadcast by cycles of electromagnetic energy directly from a metallic string to be tuned to the transducer of the instrument, and blends with a correlated note as it issues from the same said vibrating metal string to be tuned, and through discernment by the ear of the user of the resulting blended signal the string is adjusted as necessary to match the two notes and therefore the string is quickly and easily brought into tune with the fundamentally correct note frequency, and when repeated upon each string of said instrument the task of tuning is done.
