The world's top-selling stage tuner, the BOSS TU-2, evolves and improves with the debut of the new TU-3. Housed in a tank-tough BOSS stompbox body, the TU-3 features a smooth 21-segment LED meter with a High-Brightness mode that cuts through the harshest outdoor glare.
Boss makes the best pedal tuners and the TU3 is just their latest entry into the Tuner pedal hall of fame. I picked this up for my mini board to use in my worship band. Works great with my bass and guitar. Bright led's but not blinding like some tuners, just right. Easy to use and quick to check you...

Used the Boss TU-3 last night at church and I really liked it, it worked well and more accurate than what I’ve been using
