Up for sale is a genuine, vintage J. Parduba & Son New York Double Cup trumpet mouthpiece in size #4. This is an original mid-century piece featuring the iconic "J. Parduba & Son New York" stamp and the original patent number (PAT. NO. 2018738) engraved on the body.

The double cup design features a shallow upper cup for effortless upper-register compression and lead playing, transitioning into a deeper lower cup for a full, rich low register. Size 4 is excellent for high-note screamer work.
