Features a thunder-like effect that kids love! Gently shake the Remo Thunder Tube, and the vibrations of the metal spring are transmitted to the drumhead - creating a unique sound that exists somewhere between the metallic decay of a gong and the low gurgle of a didgeridoo. Easy to play, and capable of creating a wide dynamic range, the Thunder Tube adds creepy textures and whimsical warbles to your percussion bag of tricks.
