I was back from Tenor with Otto Link STM 6* to Alto Sax. I chose a vintage Buescher Big B from 1949, so I was on the search for a uncomplicated but jazzy MPC with a medium chamber. I own an older Selmer S80 F but its too big for my starting. After a research I found the M6M, everywhere its recommended for THE Jazz MPC on Alto Sax, so I got me one. For my beginnig the M6M is a good choice, cause it is not too open but has yet a bigger, jazzier sound tham my old Selmer. It's easy to blow the hiole register and you can make it scream, swing or just whispering without any problem. And, very important to me, it has a very god Intonation on my old Horn. I'm thinking to go for a M7M in the next 1-2- Years.
