Schilke 14A Rim – Inner Diameter = .656″ (16.66 mm)
Our S14A VR Flex trumpet mouthpiece is a great choice for a player who likes a traditional Schilke 14A4a but is looking for more sound and flexibility for less effort.

Players coming from a Schilke 14A4a or equivalent report our Flex S14A VR is 10-30% easier to play with better intonation and a more resonant sound.
This is due to our advanced acoustic design and Flex Alloy.

Series Design (Mouthpiece balance)

By developing mouthpieces as complete systems, or series, we have been able to combine the best internal shapes and sizes to maximize the performance of each mouthpiece. In this manner you are assured of a mouthpiece that has been balanced acoustically for maximum sound and ease of play.




Silver plated, Gold Plated

Flex Alloy

A proprietary brass alloy and treatment. It is extremely resonant and transfers energy very efficiently thus adding to ease of play.

S14A VR Vs Series

Our Vs (Speed of Sound) Series great for Lead Trumpet, Amplified Music, and Pit Work.

S14A VR J6 Series

Our J6 series is good for Lead Trumpet, Amplified Music, and Pit Work. It has more "core" to the sound than the Vs. Some say it requires a little bit more air than the Vs.

S14A VR M4G Series

Our M4G Series is the latest development in small volume cup acoustic design. It provides a huge resonant sound with an extremely easy upper register.

S14A VR 5 Series

Great all around Series. Very good for Jazz Trumpet, Brass Quintet, wedding, and Orchestral including C Trumpet.

S14A VR T2 Series

The T2 Series is a variation of the Vs Series. It has either a #30 or #29 bore. This affects the acoustic balance and many players say this allows them to use less air. Others report it gives them more "push against."

    Five Stars!!! I’ve been playing the Stomvi USA S14A VR Flex mouthpiece for over a year. There was no trial period or experimentation; right after getting it I put it in the horn and I’ve played no other since. My steady gig is in a cruise ship ballroom dance band and we play 3-4 sets of dance and big band music every night, with rarely a night off. Since I started playing the S14A my endurance has never been better. Even at the end of a hard night I can count on my entire range at any dynamic level. Response, flexibility, tone,pitch, slotting,simply every aspect of trumpet performance has been easier and more reliable with this mouthpiece. Thank you, K.O. and company for making my gig easier. Keep up the great work!
