I have two. The one I recently played on. It had a gel damper with no gel in it. Go figure.
I played on one in Cuba, where a person had to sit near me because the posts on the vibes would fall over some how and they had to fix the note. But that was Cuba and I felt part of the revolution! So it didn't feel as bad as it seems now!
The one I played at recently was a DRAG. However, I did something I could not have done before. I kind listened from inside and didn't depend on the instrument to give me the sound. This has taken me a long time. It was still difficult, but somehow I think I played decent solos and did some ok comping. Before I would have struggled a lot more!
How about you?
