I'm looking at used metronomes on ebay but have no idea what I should get.
Can anyone suggest me some good ones that are versatile enough that I won't ever need a new one?
Gibson Explorer
Jackson Soloist SL3
Orange Tiny Terror
Mesa 2x12

dont get the chime ones - apparently they get REALLY annoying and make you go mental. Get a good old pyramid crank one, not an electric one
I bought a cheap "Quick time" or something like that, that had a click sound, I can't stand the thing. I eventually started using www.metronomeonline.com again, until I got a good one that's has a nice, smooth beep sound.
