false teeth ...
I have nothing to offer in the mouthpiece and denture direction, but I would very much like to see what you think of that instrument when you get it and have played on it for a while.
I was VERY tempted to get that horn and perhaps add a fifth valve to it, making it more of a genuine tenor tuba. But in a long conversation with Tom McGrady I was warned off of it and instead got the compensating euphonium I am playing now. Tom told me that he had stopped offering the "baby tuba" at Mack Brass because of of the terrible intonation problems that afflicted the ones he had dealt with, and he sold his last one on eBay for about $500, saying that it could potentially be turned into a good instrument with some significant effort in changing slide lengths.
I would still be interested in getting one of those horns (e.g., from Wessex) at some point in the future if they do have reliable and correct intonation -- and adding a fifth valve to it, of course . So please post your impressions of it when you get a chance.
