I have recently purchased a Tube Zipper, and to my surprise it cam in a huge wooden box with the face of it painted on the lid. I know that EHX used to put there pedals in these before switching to the cardboard boxes. I was wondering how long ago the quite, and how long has the tube zipper been out?

Basically approximately how old is this pedal? It isn’t too old of course, but I love the box and would like to pick up other EHX gear that includes it. Thanks for your help guys!
