"The Big Boi" Ultrabass Trombone/Euphonium Mouthpiece

thingiverse

I set out to push the limits of how low I could go on a trombone/euphonium, and standard mouthpieces just fell short. So I embarked on creating the deepest, widest mouthpiece possible that would accommodate a large bore trombone. It took some trial and error as sometimes things were too wide or too deep. But this latest version seems to be doing the trick for me. The lowest note I was able to hit with an F attachment tenor trombone was a G0, leaving me feeling pretty pleased.
