Specify the measure for the entire samba band with the Meinl SU18 surdo. This 18 x 22 inch surdo is equipped with a synthetic batter head with a light damping. Give dull full bass beats and determine the tempo of the music. Meinl has made the shell of the SU18 from aluminum, which ensures good sound projection and very pleasant playing comfort. Transport is also easier as the product is made of aluminum.
