I've been thinking about buying one of these and putting EMG-MH (minihumbuckers) in as an upgrade; with the active EMGs then I could use tapewounds without any tapewound hum issues (due to the inherent lack of string ground you get with nylon tapewounds!) I know the MH configuration isn't visible on the EMG website but I wrote them last week and they confirmed that it's still possible to order them. I guess the real question is: are the Gretsch pups traditional mini-humbucker size, or a little different?
