Ive had this 544 series for about 5 years now. Ive noticed last summer and this summer that when its really hot ( 90 degrees or higher) that my horns have a more higher pitch note than normal. What could cause this? Are they going bad? When its cooler/cold weather they seem to be louder and have a deeper tone.
Sometimes hot/cold effects sound. The horns are not going bad, I’ve beaten mine up pretty good and they still functioned perfect right before I sold them.
