If you want to place one or two holes to you head of bass drum, Bass Drum O’s protectors are the perfect solution. They look great, of course, but they also protect the decompression hole of breakages especially when you're going to place or move something inside it like shutters or microphones.

The installation takes only a few minutes. Place where you want the hole and draw a ring along the inside. Then cut the hole with a knife or a cutter. If you're too small as many of us in Tam Percussion, you can make it easier the things with the special Cutter of holes Bass Drum O’s (not included, sold separately). Two strong adhesive rings keep the Bass Drum O's in place, so it won't move when you put a pillow or microphone.
