The Thomann CM-10 metronome has a clip on that attaches it to the headstock. The metronone has a display that does not damage the eyes, even if it doesn't work in the dark. It is really loud, as the volume can be set to play along a big amp, and has a really digital sound. It is made in China but from really resistent plastic. It works with CP 2025 batteries that last for a long time. There is a red LED that indicates the rythm. Various rythems can be played and the selection menu and the buttons are east to operate. The metronome works well, it is very stabile and durabile.
