Ken Beason said that my 103K Mark VI was one of the darkest he had ever played. Not stuffy, but dark. He described it as dark and very powerful. That was fine by me, in line with my sound concept at the time. Not so much today. It's outfitted with plastic flat resos and I'm wondering to what extent large domed metal resos might brighten it. I expect I would have to repad it, but that's okay because I'd like to outfit it with roo pads anyway, because I like their feel.
