Matt did all of my recovery work. If you go to his web page all of the green glass and turquoise glass Gretsch drums are mine. There are a lot of them. He is meticulous. The glass wraps are thicker and caused me to have to move to Aquarian American Vintage heads for fit. That said, no one would say my drums lack resonence. They are very live and I'm quite happy with the look and sound. None of these pieces are going to be sold, unless my kids want to after I'm gone. I would never recover drums in anticipation of selling them. Unless you are doing the work it is not cheap and I couldn't imagine selling them high enough to re capture the cost of the drums and the recovery work. If you buy a bass drum for $200-400 and spend another $300-400 restoring it, how can you expect to sell the drum for $500-800. Multiply that cost for a whole set. When you get up to that price range it has to be collectable and recovered stuff usually isn't.
