Your right. Those guys don't care about fragile stickers. In fact, I've heard rumors they have been known to purposely abuse boxes with fragile stickers.
I mailed a guitar last week in a used box. Every side had a fragile sticker. I took a Sharpie and scribled them out.
Anyway, I hope you enjoy the amp. I've heard a lot of good things about them.
I'm actually waiting for FedEx right now. I'm waiting for my NGD.
