I just got my hands on an old marching snare (no badge, but looks like it could be Gretsch), and as you can see in the photo the hoops, particularly the bottom one, are warped and squashed from years of too much uneven tension.
Is there anything I can do? I would love to keep the original hoops with the drum, so I'm wondering if there's any way to at least bring them back to straight and flat. The divits from the claws don't bother me so much.
If you've got any ideas or experience, please help!
