As a professional saxophonist of with over forty years playing experience I couldn't resist purchasing this sopranino just to see what it was like. I currently play on a Buffet Prestige Copper-body Alto, Selmer Balanced Action Tenor, Yanagisawa Sop and Bari and have owned Selmer MK6s,Conns, Yamahas etc. over the years. I have only ever played on Selmer Sopraninos and found them to have 'wild' intonation and not to speak well in the highest register.
What a revelation this little Thomann instrument was. Straight from the case, and with the mouthpiece and reed provided, it sang from top to bottom. It was easy to control the intonation and to produce a rich and full tone. The key action is smooth and fast..... what more can I say except what a bargain this is.
Down points, well only that the finish, although well plated and looking great with the red-brass body, is a little rough in places on the side keys but I play the thing and don't just look at it so.....
Warning! Just because this instrument is small doesn't mean that it's good for children to learn on. Sopraninos are very difficult to play in tune and to produce a good sound on. A highly developed embouchure is required and a good ear. Without these things you might wish you'd bought your child a violin, it would be less painful to the ear!
