Re: Martin Indiana Tenor x Conn 16M
The Martin Indiana was considered a step down model from the Pro line of Martin at the time. BUT, the only true difference is in key work additions in the pro line, such as an ajustable thumb rest, a double socket neck, and more elaborate engraving and pads with resonators.The sound produced by the same Martin Brass was basically the same as the pro level horns. Made like a Sherman Tank.
The 16M is Conn's tenor design, AFTER the company had already passed its peak. It was an inferior horn to the "Legend" of Conn. Most were made in Mexico, as Conn was declining in the market and are OK student horns. The Mexican brass makes them less desireable as a horn to play and simply are made cheaply. Yours is a USA version, so the sound is not the worse but not the best either. They are made like a shiny brass bucket.
My experienced is based on 35 years of playing and owning Martin saxophones. I have 2 altos and two tenors. I have a few horns lets say.
Also, for 25 years I have been refurbishing vintage saxophones.
Ironically, the older Conns, up till around 1950 are the more desireable of the vintage saxes. That was when Selmer took over the Saxophone market with the release of the Mark VI. Conn just went into decline from there.
