Oswald Knaap

"Dear Sir, I recently bought a JJ DV 8* tenor mouthpiece and it is by far the best mouthpiece I ever played on!(I am 56 and play for about 35 years).What a delight to play. All the things you say about it on your website are true as far as I'm concerned. It is totally free blowing and has an infinite sound and enormous power and projection. Through the whole register there is a rich mixture of fatness and brightness while every single tone keeps its own unique color en 'feel'. When I play something is happening to me, I am in a flow, even my fingers move with great ease, effortless. This sound is me! I'm not a pro and since a bought this mouthpiece I feel frustrated that I can't play all day..... I am grateful to you Mr. Espina and I want to thank you for your dedication, expertise and mastership in developing this mouthpiece (and the others I am sure). I am curious about the other tenormouthpieces, when I am in the shop again I will definitely try them. With kindest regards, Oswald knaap"
