Boss DB-90 Dr. Beat

I had one years ago, which broke down, and was quite happy to find it back on the market!

A very good metronome. I only found one weak point. It only has a top mounting screw which makes it much more difficult to mount next to a drum set unless you purchase an expensive clamp to attach it to a hit-hat or cymbal stand . A bottom mounting screw would allow it to be fixed to a cheap practice pad support or cymbal stand.

It is always easier to support something from underneath than it is from above.
