The Love Vibe and Ed Smith
Ed has embraced the Malletech Love Vibe and done some great things on it. I think he understands the instrument more than anyone. I think it was sort of develop with him in mind by Leigh Stevens.
Check him out. Since Ed is not a straight ahead jazz vibes player he has a lot more time to write and work on getting different sounds on the instrument. It seems to me if you're a jazz vibe player you're working on tunes, learning music, remember tunes and thinking about new techniques is not at the top of your list.
Just my 2 cents here, maybe other pros think differently. But Ed is great.
