I want to share my experience with Gator cases. I will attempt to be brief. I had one of my kits that I occasionally gig with, stored in my Gator hardshell cases. I recently took them out and was shocked to find corrosion on my floor tom. I suppose I should add that this kit is not one of my vintage kits, but my Dw's that I bought not quite 18 months ago. I couldn't freakin believe it.
I emailed Dw, and within 2 days I received their response. They asked for pictures of course, and also asked if I had ever stored them in Gator cases? Holy crap! Sounds to me they know something about these cases. I just emailed the pics off today, so i haven't heard the explanation on the cases yet.
My purpose to posting this is two-fold.
1. Has anyone ever heard of this being an issue
2. If you are using the gator cases, I strongly recommend removing your drums from the cases until we get to the bottom of this. I will let everyone know what Dw says as soon as possible.
