Will add more as I remember!

I do understand what you say. Of course, an ancient yutz like me doesn't know one format from another....

lydian-- If it gets far fewer traffic than other clarinet forums, why is it "far superior"? Due to the lack of threads/posts I may visit here once a month. Maybe time to change the situation? You said you'll try to post more, which I look forward to. Others need to take notice as well.

It's not entirely easy to separate personal instruments from historical oddities and repair inventory.

I have six metal ones, and two wood ones that are worth mentioning. Two plastic sopranos that are playable that I plan to keep, and a plastic bass.

Never been.  Seems like it would be fun.
