Prototypes of both have been made, I think the k con might actually go into production. There are a few Memphis drum shop videos on that one.Pics?
Tape on bottom should tame it, but only if it already sounds good (besides the ringing part).
I wish Z would make 22 China’s now. I love the swish, but a regular 22 would be nice...Kerope or K Con. Paul...are you out there?
Orherwise, get the A Swish Knocker. I love it!!!! Peter Erskine style.
