Glad to hear anyone has heard of a greenback AT ALL around here, sometimes it seems im the only one getting into that godly tone :P
Anyway, it took me several years to get the voicing on those right to my ears so i do understand it would not have instant appeal. They do however cover any vintage sound there is, especially the old, well broken in greenbacks just have so much righteous tone magic in them anyone giving them a true chance will get hooked for sure.
