Like the previous reviewer, I too find the metronome to be too quiet, at least for a trumpet player. The volume is turned up full but I still cannot hear it.I question the accuracy of the tuner. My current trumpet is of the low-end, and I suspected it of playing a little flat, but the tuner tells me it's at least one full step below. Based on my neighbor's piano, it's not THAT flat.Don't make the same mistake I did.
