Remo’s Rhythm Lid® Drumhead with the Comfort Sound Technology film produce a big vibration with a focused, controlled sound that delivers warm tones 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 with Comfort Sound Technology as well as with 4 types of Skyndeep® bright, medium, and dark. 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.
