Clark Fobes Blackwood Extension for Eb Sopranino Clarinet in Original Packaging

This is a neat invention from the shop of Clark Fobes. This is an extension for the Eb sopranino clarinet. It goes between the body joint and the bell, and it does a couple things for you. If you've ever noticed how the long B natural is more resistant and has a different timbre than the throat tones, this extension is meant to alleviate that common problem. This one is barely used and looks new, and comes in its original packaging.
