Gamma replaced the clamp, no questions asked.
The first post, with the exploded bearings, happened to the second clamp, which still semed good when I had the first one replaced.
Again, clamp replaced no problem.
Current clamps are fine, so far. I think the originals were just part of a bad run, perhaps.
btw, this is just an FYI. Gamma was excellent in the Customer Service and
sent out clamps quickly, even threw in some string I'm currently playing.
