Installs easily into almost any electric guitar.

N-Tune is the world's most convenient solution for fast, accurate guitar tuning. Whether you're in the studio, on stage, or just practicing, simply pull your guitar's volume knob and use N-Tune's super-bright display to silently tune up in seconds. Then push it back down to play -- with perfect tone, thanks to N-Tune's true bypass design which removes all tuning circuitry from your guitar's signal path.
