what year is your horn? I have an older pt6 and i have trouble with some notes. Do you have many dents in the horn valve work? sometimes that can have something to do with it. I have a few dings in my fourth valve and it makes it quite raspy. also your rotors might be worn. I've already replaced one of mine because of that same problem and it only happened inthe low register not on every note. just some questions for thought get back with me and maybe i can suggest good repair person for the job if need be.
