Talk apples to apples..........if you sell a homebuilt car calling it a Shelby AC 427 Cobra then there would be a problem if the owner had that has the phrase trademarked, didn't grant you permission to use it.
The issue at hand is trademark infridgement and "DUMBLE" as referenced to musical gear is trademarked. So unless eBay wants to risk being complicite in a trademark infridgement case, they are going to pull the ad.
So before you rag eBay, maybe you should contact HAD and tell him that you would like to challenge his registered trademark in court because you think the principle of intellectual property, copy and trademarks rights plain sucks. As a patent holding engineer, I don't fault anyone for enforcing their rights.
