I have started using a Curry 3c in place of my bach 3c and find the rim more comfortable and playable. However, my teacher and another pro who helped me A/B them found the bach sound was more resonant. I tested on both a schilke B5 and an LA Benge 5x with the same result.
I had the gap for both mpc checked and they were fine in both horns.
Would a bach blank make a difference with the curry rim? I'd really like to stick with the Curry but still have the sound I want. Or is it a matter of adapting over a longer period of time ?
Your thoughts most welcome!
