They Have been making this sound when aired up to 135 psi once it goes down after a few honks they sound right. I guess I have a defective horn? I haven’t honked them for about 3 weeks! hmmm.
Edit: I fixed the problem, I had too long of air line going to the longest trumpet, I shortened the air line to it and remounted all the horns and now it sounds clear and loud as day.
alright, today I tested the horns out one by one, it was the longest one, but to fix it I shortened the air line that goes to the longest one and now it sounds like it should, I also had something blocking the horns too so now I remounted them so now they are loud as hell once again!
