Mt. Vernon Bach 5 Rim – Inner Diameter = .655″ (16.64 mm)
Our 5 DVR is extremely popular for chamber music and pit work.

Players coming from a Bach 5C or equivalent report our Flex 5 DVR 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.

    Changing to the Stomvi USA flex mouthpiece (5DVR with 4-5 couplers) has been the most transformative move I have made as a professional!
    It gives me the core sound, evenness in all registers, and flexibility I need for both classical and jazz situations. Simply talking to K.O. about the properties of mouthpieces and their effect on playing has been an education in itself, and I have never met another individual so knowledgeable, honest, and trustworthy about the REAL issues of equipment and trumpet playing. Simply put, I am enjoying playing my trumpet more now than I ever have, and with the flex I am afforded the opportunity to focus and concentrate on music and expression! This is the greatest gift I could be given…I cannot thank you enough, K.O.! For each according to their needs.
