That mouthpiece is amazing.
My new SL5 mouthpiece arrived at the store last Friday so when the refurbished one arrived yesterday, I had the opportunity to compare the stock version to the SopranoPlanet version.
The new stock mouthpiece is very good; I was completely happy with it and couldn’t imagine that I would like the old one better when it returned. I was wrong. I am quite astonished at how good the mouthpiece you worked on is. It sounds the same but now feels even across the range; its worst notes are now equal to its best.
I will send you the new stock SL5 so you can do the same thing to it.
Thanks for your great work,
