Trumpet Harmon Mute. !!Only been test on Bach 18037 43 bell !! For the seal pad, I use EVA foam sheet with double sides stick tape, 3mm thick. Print pad layout in A4，hold it on the foam ，then do the cutting. You need do some adjustment on the junction point to make it air tight. Change EVA_Pad_layout.txt extention to EVA_Pad_layout.pdf.
