Most Vibraphones Are Made Using Rivets. Here's the problem.
Rivets loosen and get noisy. The omega uses stainless steel nuts and bolts. It's so much quieter.
This is a musser. I like playing mussers and am glad to play them when I travel, but they make noise.
Team Omega said to Malletech, that that can't happen to the Omega. So there are no rivets on malletech instruments.
Before you buy a new instrument ask if they use rivets.
