I primarily play Bb clarinet, but play in a few local community musical theatre pit orchestras, and end up borrowing a bass. He was at an estate sale last night, and got A LOT of old clarinets (and saxophones).
I got a text message from my local woodwind tech at a music shop. I get emails from folks all the time sharing they’ve found a hidden needle/gem in the haystack of bass clarinets on eBay (or in an attic, or in a rummage sale) and asking for my opinion on it.
