Remo Emperor Smooth White Crimplock Marching Bass Head. The Remo Smooth White Emperor Batter has accentuated midrange along with great durability. Controlled high tones, a big mid range, and controlled lows, bring out the center drum tone for more presence. The Smooth White Emperors are excellent for touring due to their superb sound, durability, and unique ability to wipe clean to appear in new condition for each show.
