Tuning a guitar is easier than ever, thanks to modern technology. You no longer need to bang out notes on a piano or use an unreliable whistle-style tuner because the all-new battery-powered guitar tuners do the heavy work for you.
The best guitar tuners clamp on to your guitar and give you a visual representation of what each pitch should sound like, eliminating all the guesswork. Simply attach a guitar tuner to your guitar, strum one string at a time, and adjust the machine tuners on your instrument accordingly. Here are our top picks. (Picks, get it?)
