Thanks Marty. Bill emailed me privately and said he didn't think it was a good match. I found the effective mass for the GH228 in an old forum. It's 9.1 grams. It's a shame the manufacturer doesn't provide this info.
Doing the math, the resonance with a Shelter 501 would put it in the neighborhood of 12.5 Hz. Not a terrible figure, but I'll take Bill's advice and look for something else. He mentioned Ortofon and Dynavector as good matches. I've also read rave reviews about the Cartridge Man Music Maker mounted on a Hadcock. I'll have to keep my eye out for a used one.
