These mouthpieces are designed to be used in German style rotary trumpets. They feature a deeper, more V-shaped cup and are usually played with a slightly larger 25 throat. These mouthpieces are made with our medium large backbore. They can also be used on piston trumpets to produce a darker more mellow sound.
Note: Some rotary trumpets have an extra deep receiver. If your mouthpiece inserts more than 1.25 inches (32 mm) into the receiver you should request a long shank model in the order notes at checkout.
