Overpriced to begin with. Didn't look sturdy or reliable out of the box and eventually did fail on me by tuning me in false pitches. Music is my life and I've owned a lot of products from different manufacturers. I'm here to say that I'm done with Boss. There are much more reliable products out there.... Maybe I rated the TU-15 too harshly, but then again, why would I give a better score to a product that is of the poorest quality brand of gear that I have collectively owned. Beware.
