I may be the odd man out but I have never played an OM style guitar that liked to be strummed. Except one. The Yamaha OM sizes, but they are deeper than the traditional OM size guitars. Or 000, or 0000 if you will. I call them all OM size because I just don't know any better.
I recently picked up a Guild GAD 30R that sounds great finger picked, but try to strum it and it barks back. Like a dog barking with a sore throat.
It's a shame you bought an expensive guitar you don't like and most likely never will. I know a guy who has a 2014 D 18 for sale what I would call cheap. I just bought his HD 28.
