The CB 4280 13 inch. Gladstone Style Practice pad is great for beginners and intermediate players alike. When you have to practice on the go, have limited space, or need to perfect your snare drum rudiments without waking up the entire neighborhood, this rubber practice pad fits your 13 inch. snare drum perfectly. By placing this pad on the snare drum, it mutes the top head completely and allows your sticks to bounce back with ease just like a regular snare drum.
