The Grover Pro Rolling Gong/Tam-Tam Mallets are designed from the bottom up to create lush, connected rolls on a gong. The 3 1/8" head and 5/8" lightweight aluminum handle are home to a solid rubber radial core covered in felt that makes rolling feel easy and sound great. As an added bonus, the metal shafts won't wear down outside, making them perfect for marching bands and drum corps!
