Sure, you can carry around a tuner to help you get your strings back into musical zen, but why have a separate item to lose when you can have it built into your guitar? I’ve seen guitars that have built-in tuners from the factory, but these tend to be acoustics, where they can afford to hide extra electronics inside the hollow body itself.
Well, for $70, you can purchase a DIY kit called the N-Tune, which is a tuner with a ring of LEDs, built into a volume knob that matches Gibson or Fender electric guitars.
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.
N-Tune is available as an aftermarket kit that can be easily installed into almost any electric guitar. All you need is your existing volume knob and some standard soldering tools. Best of all, no permanent modification of your guitar is required!
