The Michael Rath mouthpiece range was introduced in 2004 after extensive research, development and testing. Our goal was a very simple one - to create a range of mouthpieces that not only would perfectly compliment our own instruments, but also would be excellent mouthpieces in their own right.

All Rath mouthpieces have had substantial input from professional players in their design and many of our models are “Signature” mouthpieces, designed in collaboration with Rath trombones artists such as Mark Nightingale, Mark Frost, Bert Boeren, Marc Godfroid, Mike Dease and Brett Baker.

Rath mouthpieces feature a semi heavy outer shape, designed to bring the beneficial features of heavy weight mouthpieces, such as added projection and core to the sound, without reducing the feedback to the player, as can be the case with heavy weight designs.
