Today, while playing my Mapex Black Panther Sledgehammer, i repositioned the snare on the stand to make it a little bit lower. When i took the snare drum off, i noticed 2 of the snares were broken. I'm not sure if they are broken, but they are definately unattached to the other end. I guess I have to buy new snare wires, but I've never had to do that before and I'm not sure what to buy. Can anybody help? Thanks.
