What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Measure the shell diameter, not the old head's outer flesh hoop, or you will order the wrong size.
Detail 02
The standard marching bass look, and it stays visible on a dark field under stadium lights.
Detail 03
Sized and built for a drum carried horizontally and struck with mallets, not a pedal-driven kick.
Detail 04
A marching bass drum takes a head on each side, so one drum can need two.
Detail 05
Re-heading a full five-drum line runs into several hundred dollars, so budget by the drum, not the head.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It is a 20-inch head and will physically seat on a 20-inch shell, but it is built for marching bass drums played with mallets rather than a bass drum pedal.
No. This is a single head. A marching bass drum takes one on each side, so order two if you are redoing a whole drum.
Measure straight across the drum shell itself, edge to edge, with the head removed. That number is your head size.
A drum key to loosen and retension the rods. Nothing else.
