The New Standard Floor Tuner!

When the TU-2 was introduced in October 1998, it was met with overwhelming success: an indestructible tuner in the popular Boss pedal format... it exploded onto the scene, quickly appearing on stages worldwide. Amateurs, pros, and guitar heroes alike included it in their setups. The TU-2 was the best-selling Boss pedal worldwide every month!

Since then, many manufacturers have built similar tuners – but now Boss presents the TU-3, raising the bar significantly with fantastic new features, a reduced price, and the same rugged, reliable quality!

This product is absolutely recommendable. I watched a few YouTube videos beforehand and came across the BOSS TU-3 Chromatic Tuner by chance. I liked it right from the start, the features are sufficient and the device does what it should.
Unbeatable for the price.
Alles okay
