I need advice on a replacement MPC. Current MPC is a Conn Precision with a 3 on the MPC. This MPC has deep tooth gouges from a previous player and the tip is uneven to the naked eye. I am learning to play jazz. I want to keep the horn's deep warm tone. I can't find any charts to indicate the tip opening size for the precision so I have a point of reference for selecting a new MPC. Seeking input on tip opening and MPC models brands.
