That's a good link, Ed. I'm actually thinking of getting a metronome as well. When I play with other musicians there isn't such a problem but if you jam away on your own for a long time you tend to develop a lot of off-beat rythms. I went around and asked about the old-fashioned tick-tock kind as I have an irrational belief they are better. Better they may be, but I had to clutch onto nearby sheet music stands for support when they told me the price..! I thought the electronic one would have been more expensive and fancy, but apparently not. So it looks like electronic is the way to go. I just dread getting an unreliable thing that looks like a prop off Star trek and that will make some horribly annoying sound...!
