I have been playing the french horn for 35 years.
I occasionally continue my quest for a better mouthpiece, so I thought I would follow Sarah Willis & give this model a try.
The McWilliam 1 could be the perfect blend for me.
I can reach the highest notes, I can reach the lowest notes.
I can play softly, I can play loudly.
I can slur, I can attack. It is comfortable on my lips.
I use an Alexander double horn, and can make it sound both brassy & smooth.
There are many mouthpieces that are close to this one, such as
Bach 7, Paxman 4B, PHC 22A, Schilke 30, however, this one feels like the best blend of dimensions.
It is also nicely finished & fits the horn correctly.
