Kenji perform on stage everyday, found out that every time when he is cross-sticking, the audience and the band mate couldn't really hears it, he needed an enhancer ..That's why we recommended him to try TheRimRiser ! it works for him! Surprisingly when he is doing some cross-stick pattern, it gets smoother because he got more grip on the sticks. he loves it! and Bought it home! Thanks Kenji!
