It has a small shank trombone receiver (smaller than typical "small/British" tuba shank), but it does include a mouthpiece that fits the instrument. Find a custom 'piece and use it as a poor man's cimbasso. It can get fairly bright. Plug in a 6-1/2 AL and fire away!
I'd like to get $200 for it. Pickup in southeastern CT or I can meet you in the NYC Metro/New England area. PM or email beanhillbrass at gmail if interested. FedEx shipping may be possible at buyer's sole expense and risk. Thanks!
