I bought the metronome / tuner, because the last few months I'm learning trumpet and wanted to practice myself in the meeting of precise tones. For the tuner is perfect. With the folding stand can position it well and the sounds are displayed in parallel to play. Besser gehts but not at all! Now that I'm playing my first songs the metronome is used. The large, round button, which allows you to set the pace yourself is to simply awesome! So-and is easy to operate, although it has so many features! The unit I would definitely recommend!
