The surdo is the biggest, deepest drum and plays the heartbeat of samba music. This set of three practical Castle surdos includes one green 14" drum, one yellow 16" drum, and one red 18" drum.
Unlike the other ranges from Izzo, these drums have a skin on one end only, meaning they can be stacked away inside one another to save space and ease transportation. This makes them particularly suitable for classrooms with limited space.
Of course, removing one of the drum heads causes the tone to become brighter and more resonant. To compensate for this, each Castle drum is fitted with black Napa rather than standard synthetic skins.
Rubber feet are also supplied to protect the drums (and the floor) when being played on the ground. Take a look at the links on the right hand side of this page for sticks and straps.
