I just got a used YTR-6445H C Trumpet. I was in lessons today and realized my teacher had the same horn but had it opened up a bit with a Bob Malone Lead pipe setup and a different tuning slide. The brackets are also moved around a bit along with different sleeves for the slides. I am looking for someone that can do a setup similar to this for me as my horn is very stuffy and not very resonant. I am familiar with Blackburn but are there other companies or people that are well known for making these types of setups.
