I want the rim to be size 594, which I believe is Jason’s custom rim size. Besides that size, I would like to have the contour of the 1SB Super Chops rim. Can that be made? I currently have a 614H rim and spectrum cup R614B. This 614H rim makes the mouthpiece feel like it's a big mouthpiece like a 1.5 Bach mouthpiece. Feels uncomforatble in playing lead.
