The Personaline is one of the best vintage alto pieces for a balanced, projecting alto tone that doesn’t sound just like every other mouthpiece. It was Brilihart’s top-of-the-line in its day, and is well made with the marbled tooth guard and gold lettering. The L5 is a comfortable .067″ tip that is around a Meyer 4. Works great with a medium reed. The oval-shaped medium chamber has a slanting floor and and slanted down side walls. I like this piece for its crisp, lively alto sound and for being nice and easy to play. The facing is original and cloudly looking with curved machine marks. There are a few tiny nicks in the outside of the rails, but nothing that affects playability.
