Detail 01
Measure the drum shell, not the old head's hoop. An inch off and it will not seat.
Detail 02
Standard marching look, and it stays visible under stadium lights. Matches other white heads on the line.
Detail 03
The Yamaha logo faces the audience on the outer head. Matters if your line runs matched branding.
Detail 04
Built for the tension and outdoor swings a marching drum sees, not for a kit bass drum.
Detail 05
A marching bass drum has two heads. Replacing only one leaves a visible and tonal mismatch.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Measure the drum shell diameter across the top, not the old head or the hoop. Head sizing follows the shell. An 18-inch drum takes this head.
No, one head. A marching bass drum is double-headed, so order two if you're replacing both sides at once.
It's built for marching bass drum tension and outdoor use. A kit bass drum head is a different design and will give you a different sound and feel.
A drum key. Take the tension rods down evenly, seat the new head, then tension in a star pattern so the head sits flat.
