they look for a variety so show them various styles that you can do. i myself used to be sponsored by istanbul agop cymbals but even with the discount, i couldn't afford the cymbals so i had to leave. anyways, what i did was i sent them a press kit which included EVERYBODY i have played with, what styles of music i play, photos of me, as well as a tape/cd of my playing so they can get a feel for what i could bring to the table. they then decide whether to endorse you or not and if they do, you will then be put under one of three catagories, and A endorsement means that you are getting major nationwide exposure and that you are touring, etc. this will give you FREE gear. a B endorsement means that you are playing with a lot of famous people but not getting as much exposure. this would give you like a 75-85% discount on their products. if you went on tour as a B, your level could be bumped to an A. then finally, there is the C endorsement which usually mean that you get a certain percentage which is usually around 50% of when you purchase there products, i hope everything works out with you and that you get that endorsement.
