I have the MST STUDIO R N, for bass trombone, after testing it well, I can say that, It has an extremely comfortable rim, well balanced cup depth and bore.
In the orchestra it allows me to play at all extremes in a spectacular way, the fortissimos, everything and being a conservative mouthpiece, as far as sizes are concerned (it is not huge like other models, or as fashion dictates) it allows me to play them huge and with a perfect body and the pianisimos preserve the body of the sound without blurring.
all this with a bright and beautiful sound (at least that is what this mouthpiece produces for me, for someone else it may darken the sound or a thousand other possibilities)
In short, balanced, comfortable and very versatile mouthpiece.
Thank you Markus for the attention!
