The Daddy-O is a great all-round, classic full bodied alto mouthpiece.

From the designer, Mark Sepinuck: “Daddy-O alto mouthpiece: Highly versatile and flexible alto mouthpiece that produces sounds that range from sweet, warm, and colorful to modern with some nice brightness, great clarity and punch. That’s why this is my all-around mouthpiece model. All the power necessary to lead a modern big band section through modern playing situations. Very versatile and classic sounding. An all-around mouthpiece like this should sing and ring, whether it’s warm or brighter! You can get all the classic alto vibes from this piece, but this has more power, clarity and freedom in the blow. If you need even more aggressive, just go with the Showboat model. Its that simple a choice. Bird, Stitt, Hodges, Desmond, Art Pepper, Lou Donaldson, Phil Woods, Cannonball, Charles McPherson, and Dick Oats vibes are certainly all available with this Daddy-O, to name a few, but this will have more punch to the sound than the Alto madness model, and less than the Showboat model. As always, it depends on what the player brings.

An amazing alto mouthpiece with a harmonic richness not found in more traditional designs. You can play as quiet as you want and as loud as you want and I designed it so it would not be as bright or punchy as the Showboat model can get, but still have lots of volume, killer altissimo, and more power available than most straight-ahead alto players have experienced from the vintage models. For me, it’s so much more fun and satisfying to play than any vintage Meyer Bros and all the Category 1 vintage mouthpieces. This includes Brilhart, Selmer, Meyer, Otto Link, etc…, while keeping the tradition and classic alto sound associated with those pieces available. This piece can sing over a big band section or whisper as soft as you can.”

It’s great to see 10M Fan expanding into alto mouthpiece manufacturing as it’s now possible to play with that trademark fat and full sound on alto as well as tenor. This piece for me has that real Phil Woods style tone, a lot of Meyer-like qualities in there for me. The bottom-end of the range is particularly full and broad. Within the whole sound is a built-in resistance that’s above medium for me, and I do like this except that I wouldn’t personally opt to go higher than a 6 as I believe that you have all the power needed at this level and pushing beyond this tip would create too much of a forced blow.

Overall I think this mouthpiece is excellent, and I found that the more time I spent with it the more I engaged with the different layers of tone that are available to you. Beyond its natural full-sounding starting point it can really sing with a strident and singing solo voice. - Jim - sax.co.uk
