One of the best tuner pedals!

Product Review

I have used other chromatic tuner pedals but the Boss Waza Tuner pedal is the best. It is so easy to see how far off a string is out of tune. The Waza pedal is better than Boss’ regular tuner pedal because of how easy it is to read, even in darkened stages! Get it! You’ll be happy with your decision!
