I've still got my Wittner pyramid from the 1970s. It was a cheap veneered version. I've been keeping my eye on a solid walnut version as a luxury. It's a nice bit of furniture for the top of the piano, although my piano is only electronic.
But I was wondering if mechanical metronomes are obsolete. It might be silly splashing out if everyone else in the world uses electronic or a Snark or a smartphone or a website. What are the pros and cons of mechanical and electronic? (solid wood Wittners are about £120 at the moment, if you are out of touch and don't know) (you can also get plastic mini mechanicals and so on)
