I have been playing on the professional unlacquered model for two years now and have loved every moment of it. I played it in a paid college ensemble, and the range, depth of sound, dynamic ability, and consistency has made me a lifelong Jean Paul user. I truly cannot recommend it enough.
Playing in a college band, we swing those things around, dance, set it quickly up and down, put it through freezing and hot temperatures, and it has withstood everything. Rain or shine, the outdoor bands play and I know it is always ready for what I throw at it.
And the mouthpiece is comes with too is reliable as well. By far the best set up yet.
