Haven't heard of it, and don't mean to be a jerk, but . . . We should just have a contest on SaxQuest to see who can legitimately claim having owned or played the most obscure saxophone. Categories such as type (c-flat melody ? tubax, straight sax, etc. ) and brand. The Thomann TAS-150 (T Alto Sax??) could be a cell phone advertisement for all I know.
