To use the Snark Tuner effectively for tuning your instrument, simply clip the tuner onto the headstock of your instrument. Play a note and the tuner will display whether the note is in tune or not. Adjust the tuning pegs until the tuner shows that the note is in tune. Repeat this process for each string of your instrument.
