Developed by Vandoren in 1983 for jazz and popular music.

thicker extremity and a more flexible pallet* than the Traditional reed allow vibration over a larger surface area with maximum elasticity.
This type of vertebral column gives the musician much greater playing flexibility, as the resultant elasticity zone is very large.
The JA stands for Jazz and the VA stands for Variety (entertainment music) and ...Vandoren.
The Vandoren Java reeds are more flexible than Traditionals and V16s and vibrate on a long pallet, creating a bright sound with immediate response.
Available in strengths of 1 - 5 and in boxes of 10 (soprano and alto) boxes of 5 (tenor)
