I needed to figure out a way to have my b/o badge 13'' tom visible from the front without having to use a snare stand or worse a rims system. I'd heard about the Ludwig Atlas mounts, so I went out and bought one. You just remove a lug and it fits right into the existing holes. The bottom screw actually moves up or down to fit any hole pattern. It's a little heavy and bulky, but it works great. I highly recommend them.
Now if Ludwig had just followed Rogers lead and put the badges on both sides of the drum this wouldn't be necessary. Sumo Dude
