The KELLY-SCREAMER is a lead-trumpet mouthpiece design. The rim has a remarkably cushioned feel that still provides good
slotting and great note accuracy. For comparison, the diameter is near a Schilke 13a4a with the KELLY-SCREAMER being a bit
shallower. The throat is slightly tighter than a Shew-lead, and the parabolic backbore just under that of a 3E. But please – try one
for yourself!
