The same thing I think about bad organ sounds in any music. I can spot a fake organ from a mile away. Since we've been together, my wife hears organ in songs all the time. She always says, "I'd never know what that was if it wasn't for you..." and I'll say, "Yeah, but it's fake."
"How do you know?" she says?
It's pretty obvious to me. Organ sounds have been notoriously hideous for a long time. It's only with the recent releases of clones, both hardware and software, that things are looking up. But they all still wither when compared to the real thing.
I have a Roland VK-7 that I can hardly stand to play anymore. The thing sounds like shit. But every now and then I get a person at a gig that says, "Man, that organ sounds great! It must be nice to not haul around a real Hammond!" and I say, "Uh... yeah..."
