Last June I bought a Bart Reiter Tubaphone while on holiday in the US, from Billy Cornette of the Reed Island Rounders of Hillsville, Virginia. I didn't think it would ever take over from my Lo Gordon, but over the last 6 months it's snuck in and become my main banjo. It had a very low action when I bought it, so I've put a higher Snuffy Smith bridge on it, and now it takes clawhammer up the neck beautifully. It's tone is very sweet and it's volume is great for playing with my Appalachian dance team, without being drowned out by clattering feet. I still use the Lo Gordon for teaching, as it has a gentler sound.
