I took my horns apart to paint them today and my p2 trumpet has two diaphrams but the others only have one. Can anyone tell me why that is? Also where can I buy new diaphrams for them?
Welcome. I know compressors, not horns, but these guys should know. If they don’t, try the hornwhistleboard forum. I’m sure they’ll know.
Thanks for the info, Ill check it out.
