Freakin' awesome! If Ondrej were coming soon I'd expect him to grab this one for his own. He's very picky, and this one is made to his specs. He loves the wood to be as dense as possible. The walls are shaved thin (1/4 inch thick walls) on the top end for responsiveness and then it thickens up through the center and distal end to contain and deliver the power. The bell is not so large as to bring in extra amounts of bass which would rob from the middle and upper range response. Matching trumpet. A very nice instrument.
