I rarely have saxophones for sale these days as I am kept busy (and usually running behind) on regular customer repairs, but if I have one it will be here. If you are looking for saxophones online, my first and strongest suggestion is to get one from Brian at Getasax.com. He is honest, pleasant to deal with, loves vintage saxophones, is super knowledgeable, and has a good return policy. He also has a good deal of my time reserved (he waited like everyone else) and you can have him get me to overhaul a horn you are purchasing from his site- I charge him my normal price, he charges you exactly what I charged him.
Horns currently for sale (I actually have one!):
Couesnon Monopole Alto Saxophone, original silver plate, high F#. $2600 incl. overhaul. (full listing coming soon)
