I have a friend that told me about his son and the trouble he had with the GPR hard-shell cases.
Apparently, the cases are made with an adhesive that somehow ruins your hardware -- it pits your chrome -- hoops, lugs, stands, any plating surface.

He told me Gator replaced his cases with a new line and gave him a check for more than his drums are worth.............he has a set of Gretsch and a set of Yamaha and they were both damaged.

Anyone here heard of this ?

You can Google "gator drum cases lawsuit" and it will pop right up as "GPR Cases Statement".
