John Parduba started making custom mouthpieces in 1915 then opened his original shop at 3rdAve, & 87 St., NYC. In 1918 where he fabricated trumpets and cornets of premium quality in addition to his mouthpieces and repair work. THE DOUBLE-CUP IN 1935 In the early 30’s Parduba moved to his new shop at 140 W 49th St., where in 1935 he introduced a remarkable new design in mouthpieces for brass instruments. This was the world famous “Double-Cup” which was unknown and not too popular until 1938 when Harry James discovered it while playing with the Benny Goodman Band across the street from Parduba’s place at the Plymouth Hotel. As a result, the Parduba Double-Cup became an overnight success throughout the country with trumpet players in many top bands. Name players such as Ziggy Elman and Ray Anthony started using the Parduba and in 1943 Louis Armstrong joined the club. The entire trumpet sections of several name bands were using these fine mouthpieces. Because of the success of his mouthpieces, Parduba discontinued making trumpets and cornets and doing repair work and specialized only in making mouthpieces. Today, by all standards, the Parduba Mouthpiece is still one of the best and most popular. DOUBLE-CUP MOUTHPIECES The unusual patented design of the Parduba “Double-Cup” mouthpiece enables a great ease of playing in the high register. This is noticeable the very first time that one tries this mouthpiece. After adapting to this design, it is possible to attain excellent control, and a beautiful tone is often realized when using the larger sizes such as the numbers: 5, 6, and 7. Although the cup appears to be very shallow, the lower half of the cup gives great length to the overall shape of this Double-Cup design which in turn produces a very brilliant yet rich melodic tone. One must be very careful not to overblow this mouthpiece since it takes much less effort to execute a tone than other types of cups. Sizes run from the No. 1 to the No. 8
