This Tuner / Metronome is great for anybody that plays an instrument, that has to be tuned. If its a Guitar, Bass, Violin, Clarinet, Saxophone or whatever you play, with this tuner you can tune it anytime and anywhere. I use it for my Guitars , my Bass, my Saxophone, my Soprano Trombone, my Violine and even for the harp, that is standing in my room. So it is just great and I love it. And the built in metronome is also great and very intuitive.
