Hi all,
I recently came across these, purely by chance:
Here's the link
As far as I know, these things are extremely hard to come by, I've tried googling for them a million times and was never able to find any - I stumbled upon this link while looking for something else.
They are for 10" cymbals (couldn't find more sizes), but at 14 euros for 3 (including shipping - the more you buy the cheaper they are) I'm sure I'll be able to find a way to put them to good use - they'd make very handy choke switches, though my intention is to use them for bell and edge zones. They still haven't arrived yet but we'll see if they are any good; my only worry is that they'll fail after a short period of time, but it's not as if I'll lose a fortune trying... Will let you know how it works out.
