A jambassador is a promoter ("ambassador") for the jam session community ("jam" or "jam session"). Jambassador is also the nickname for the ambassadors for the music jam session platform "jambassador.com". Jambassadors run around and talk about, blog, post and promote the idea of musicians from all over the world peacefully jamming together on that platform.
A jambassador spreads the word of music!
