Hey y'all, I just bought a Xeno YTR8335RGM and none of my mutes fit the bell. Has anyone else shared this problem, Flugelgirl I think you have a Xeno? What did you do to overcome this monumental issue. I love my bubble mute and I can't use it. My trumpet is the shotblast lacquer finish, I love it. It feels so solid and sounds so smooth. But the mutes... the mutes. I don't even think thinner cork will fix the problem. For the love of god can someone provide me solace in my dark place.
