Vandoren Profile Alto Sax AP3

In comparison with the original mouthpiece, this one enables you to reach the highest and lowest notes super easily even with a softer blow. Depending on the reed used, it will take you places that you could never go with the original MP. The only problem was, that I had to carefully sand the bore on the deep end (which was not that easy without proper tooling) as it is slightly conical and doesn't slide all the way on the Venova tube, even when removing the upper gasket.
