First off congrats to everyone involved! I've been a Zipper fan for along time and from what I'm seeing Bill and Tracy are the perfect folks to keep Zipper on the right track for the future. Awesome folks awesome product.
I bought my "first" Zipper not long after they first started. Bob is a incredibly talented individual. He was just dabbling in pool cues at the time, didn't know he was a luthier now. Cool link to that video thanks. Good luck, I'm sure Zipper will be around for a long long time.
