I’ve been playing on Karl’s mouthpieces since I was in grad school at IU Jacobs School of Music around 2008. I still love his pieces and work and keep extras in my teaching studio for students to try and compare to other brands. Great attention to detail, excellent to work with, and make me sound better than I should! The few times I’ve wandered away to try something new I’ve come back pretty quickly. Every recording I have of myself that I still want to listen to was recorded on a Hammond. Give them a try and see for yourself!

Karl’s hands-on approach makes worlds of difference compared to many of the other mouthpieces I have played between trumpet and horn. Greatest strength is in his custom work, as he’s customized one existing mouthpiece that later served as template for a complete custom. I don’t see myself playing on anything else, as I feel I really do Sound Better in HD.

Karl Hammond was very professional and is knowledgeable of the product line. This made my experience very enjoyable. Thank you Karl with your expertise in helping me pick out the mouthpiece best suit for me.

I got to go here with Jay Friedman in 2017 to find a new mouthpiece. Top notch craftsmanship & I still work with Hammond Design to fine tune my current mouthpieces. Highly recommend.

Karl makes mouthpieces of top quality. He also will sit with you to make sure that the fit is right for you. There isnt any reason youll need to spend close to $300 on the other brands because Hammond Design is just as good and cost less than half as much!

The best craftsmanship, quality, service and knowledge hands down! Karl is wonderful!
