I have a 1988 GK 200MB with a built-in chorus effect, and I've wondered why GK decided to add it since I've never found a reason to use it. I can't remember any recorded popular music where the bass has this effect, so does anyone have examples?
I did actually stumble on to one a month ago, I listened to Michael Jackson's Off the Wall album and learned to play the Off the Wall track because I liked the main riff. I was missing something from the sound and I hit the chorus...perfect! Maybe I'm wrong, but the bass has a very interesting dimension to it in the main riff especially.
