Great quality poor product
The build quality of the tone collar is great.
The product itself did not deliver the promise.
It does not fit a Lawler C7 (Getzen valve set).
It fits a Burbank by Kanstul, but the way to fit the tone collar may easily damage the valve caps. O-ring is recommended to avoid valve cap damage.
It is noticeable that the area around the 3rd valve was damped, the trumpet felt slightly unbalanced in vibration around the valve block. The response is slightly improved. Maybe it works better for other model but not the Burbank trumpet (X5).
