I've been comparing Hammond emulations a lot lately. Which is a surprise, given that I've had a great one in my kit for many years (VB3) and never thought I'd be researching alternatives. (VB3's successor, VB3-II has been a major disappointment and step backward.)
Blue is outstanding and I might even purchase it if they offer a nice discount for Black Friday. I am currently evaluating the Arturia offering, which has some interesting features no other faux-Hammond has, such as a modulation matrix.
