Remo’s Rhythm Lid® Drum heads with Skyndeep graphic film are weather resistant and produce warm tones that increase sound, volume, and projection in any environment and are designed to fit most U. S. made pails or buckets. Remo’s Rhythm Lid® pre-tuned drum heads are constructed with an Acousticon drum shell and are available in 4 types, Skyndeep® bright, medium, and dark, along with the Comfort Sound Technology®. They are designed to fit most 5, 6, and 7 gallon U.S. made pails. Applying the drumhead to the pail with a slight downward pressure creates a “Press Fit” seal that produces the quality tonal frequency.
