Reference series drums possess all the finest and most in-demand features from the Masterworks department. Reference 16" Floor Toms are made of 2-ply maple mixed with 6-ply mahogany; giving off fat yet controlled low frequencies and outstanding resonance. The fully-rounded bearing edges increase shell-to-drumhead contact; making the sound more punchy and with higher volume. All Reference floor toms feature Pearl Mastercast hoops, BRL swivel bridge lugs, and Air Suspension Rubber Feet.
