Found it. When I first opened it, I was really hit by the lemony hops, but in the glass it is really nicely balanced, the grain (creamy corn and biscuity malt) flavor is nice and firm, and the hops balance well. Of a spate of "craft tries to take macro on their own ground" brews (and I wholeheartedly applaud the idea) this is one of the tastiest, and maybe has the best chance of appealing to both crowds. (I read that in some markets Founders is putting this in 24 packs placed only in the domestic macro section of the beer aisle -- taking it one shelf at a time, they say.)
Two similar to this to this I've tried recently: Market Garden (Cleveland) Nano, described as an "OG lager;" I found the grain profile similar to Solid Gold, but the Founders is crisper in the hops. And I've had Four String (Columbus) Hilltop Heritage Lager, clean and crisp, but to the extent that you might not notice much difference if you just save your money and buy the cheapest case in the gas station.
I'll be buying this again.
