Boss TU-3 Review

After an amazing performance by Boss TU2 for years, an updated version of the tuner with a few extra and upgraded features was announced as TU3.

The new tuner consists of a LED stream meter of 21-segment. The screen has a high-brightness mode which allows the user to read the screen easily during daylight as well.

  • Features - The extraordinary features of the tuner like bypass option or the ability to act as a powerhouse makes it immensely useful.
  • Brightness - The adjustable light of LED brightness serves as an advantage to the users as it allows them to easily read the display in the bright daylight too.
  • Swift - The tuner is swift and thus reacts in very less time. It hardly takes seconds to perform the desired function.
  • Long-LastingThe tuner is made with good technology and provides quality functions. Thus, it will be a one-time investment in almost a decade. It’s worth every penny you spend on it.


  • SlowAt times the tuner takes almost 15-20 seconds to pick up the tune of the instrument.
  • Battery - The modes of the tuner consume a lot of battery and that too very rapidly.

Boss TU-3 thus adds up to the existing features of TU-2 to make it better and advanced.

The additional features include 21-segment LED, a high-brightness mode for daylight, swiftness, and power channeling.

Thus, when it comes to Boss TU-2 vs TU-3, clearly, TU-3 wins the match!


For years, Boss tuners have been on a “must have” list of the musicians because of their high technology and accuracy along with the extraordinary features at such affordable prices.

Boss TU-2 has undoubtedly been the star for almost a decade, but what matters is that TU3 has tried covering up all the flaws of TU2 and thus has become a better as well as an updated version of the former tuner.

So I’d personally go with Boss TU-3.
