Nothing secretive about this at all, these mouthpieces just aren't part of their regularly-catalogued items. Call them up, tell them you are interested in the Kanstul Geib tuba mouthpiece that Jim is making, and they'll take your order.

OK! Back 1/2 step! Why would a rotary valve horn respond more slowly than a piston? Is it the 180 deg. turn? Has it been measured?

Valve type is just one of several factors. Metal thickness, receiver gap, leadpipe length, mts gap, etc.

Correct me if I'm wrong, but I'm pretty sure that rotary valves only turn 90° (1/4 turn) :shock:
