What are the essential differences (aside from the name) of the two basses? On their site, I see that the Monarch has some jazz style pups... and maybe the emporor comes in both bolt on and neckthrough models? Clearly I see that the Imperial is like the "big daddy" and is Single cut, but I think I've seen single cut "others" with the Fodera name on them aside from the Imperial. I just don't get it.... Can anyone help??
