Query: Not Worth Your Money

I was excited when I bought the Korg TM-40 over two years ago, only to receive something of poor sound quality. It has many options to choose from from both the tuner and the metronome side, which I loved. But with the violin, the sound over powers the sound of the metronome. You can find much louder and better quality metronome for same or better price, this is not worth my money.
