I'm sitting on the couch and done with music work for the day but if this thread reminds me tomorrow maybe I'll post some photos and audio clips of my go-to alto piece for the last many years.... and it's an oddball. 🙂
I've been lucky to know Matt Marantz since way before he was a mouthpiece craftsman, back when he was simply one of the finest saxophonists of his generation. I was in college in Denton while he was in high school in Dallas, and we were studying with the same teacher, the great Jim Riggs. Fast forward many years and he did the Monk Institute and the Manhattan School of Music and was living in Brooklyn as a fantastic freelance saxophonist, audio engineer, and burgeoning mouthpiece maker. I had him rework a few random pieces that I'd inherited from a friend, one of them being a Selmer USA "Magni-Tone," the only one of I've ever seen. Matt opened it up to .085 (about a Selmer F, I think), my preferred tip for alto, and it's far and away my favorite alto mouthpiece ever, with no close second.
I keep an eye on the used market for Magni-Tone mouthpieces but they basically never come up. I may have lucked into a unicorn. I will never ever sell it, sorry. <3
