trumpetnick

Seems that the Schilke 11AX was designed to play on schilke pic. Probably that is the reason why it did not work as well as I wished on other trumpets (bigger bell and larger backbore for spada or different shaped bell for rotaries like scherzer). I found another one on their site which is 14A4x which may be an answer.

I thought of warburton and I consider seriously this option. Are all cups available with cornet schanks? I did not find bach 1 1/2C to their chart. My aproach is actually to get as close as possibble to my Bflat moutpiece rim size but slightly shallower.
Any one playing GR? I think of looking there too
