The BOSS TU-3S is a compact, reliable and always-on solution for musicians who want to stay on the right note.
It's good tone for any guitar player to be in tune. So that you don't waste time or space, BOSS created the chromatic tuner that fits any pedalboard. At 73mm wide, 84mm long and 56mm high, the BOSS TU-3 is perfectly visible on stages with varying lighting.
The meter is a brightness-adjustable 21-segment LED that, in High Brightness mode, makes the scale visible even when playing on a sunny afternoon.
The BOSS TU-3 is an incredibly accurate pedal, whatever your tuning. Can be used in Chromatic or Guitar/Bass mode, compatible with 7-string guitars and 6-string basses. Guitar Flat mode supports drop tunings up to six half-tones below standard tuning. And to make the whole process easier, the Accu-Pitch Sign function provides a visual check when tuning is complete.
The TU-3S is a variant of the TU-3. The big difference is that it doesn't have a switch, so it's always active and ready to use, while saving on the space and weight of your pedalboard.
Otherwise, it's a BOSS pedal, with all the characteristics that made them famous: great quality of operation, excellent construction and incredible resistance and durability, even in the most extreme conditions.
For over 40 years, BOSS has produced the most iconic pedal models that have shaped the sound of some of the most important artists of the last few decades. All its products are recognized for their high strength and durability, thanks to a solid construction, able to survive the most demanding and intense stage conditions, in a compact and easy to operate format.
Stay in tune with the BOSS TU-3S.
