nope...you need some kind of external aid...usually the note A at 440 hz. Then u tune is to the 5th fret of the Low E or fatest string. Once u have that in unison....then u tune that note with the open string below it. Continue this pattern until the 4th string from the top in which u tune the 4th fret to the open string below it. Then u go back to the 5th fret of that string and continue on. simple isnt it :)
