An evolution of BOSS's famous TU-12 tuner

The BOSS TU-12 tuner has long been a favorite of guitarists and bassists: rugged, affordable, and accurate. And now, BOSS has evolved this famous tuner, so it has even more features. The new BOSS TU-12EX now features flat tuning (of up to six half steps), so you can easily reach the right tuning when you're not playing in standard.

Accu-Pitch tuning mode lets you know audibly when you're in tune

The TU-12EX features BOSS's popular Accu-Pitch tuning technology. When your string reaches the right tuning, the TU-12EX will sound a beep to verify you're in tune. It's a very handy way to quickly tune up without having to keep an eye on a needle.

Simply a rock-solid TU tuner from BOSS

BOSS pedals have achieved legendary status for good reason: not only are they ruggedly built to withstand stomp after stomp, day after day, but they're also purpose-driven tools that deliver the kinds of tones and functions that serious guitarists and bassists need. With BOSS's line of TU tuners, you can be sure you have pro-level tuning in your arsenal, whether you're playing a sold-out gig or rocking solo in the basement.

  • Chromatic and Guitar/Bass tuning modes

Works forever, best tuner I've ever owned!!

I've been using the older model of this tuner for going on 15 years. Still as good as new! Works plugged in or with a mic, very precise and very reliable. I've used it for guitars, horns, violins, mandolins, banjos, etc etc etc. If you want a solid, reliable tuner, here it is

Great Deal for Value

An awesome tuner, a must have for it's accuracy and dependability. Easy to setup and use, but I wished the background had a different LED colour (e.g. Green) once the string is on-tune. All and all, I would recommend it!
