This is the impression I had for a month after purchase.
I feel that this instrument is optimally tuned in terms of pitch, timbre, and response.
And the reaction is so fast that it can be expressed in sound by immediately reacting to the player's image. You can feel the rich and soft sound in the entire range.
The bass and treble pitches are also great, so you can concentrate on your music without stress.
The valves move smoothly and it is easy to blow fast passages. I can understand that it was carefully assembled in every detail. I am happy with the quality.
I've been playing old rotary trumpets for a long time and wish I had used this instrument sooner.
