What's the difference between the slammer, grabber and ripper basses. Maybe I just didn't do my homework right, but by looks I can't figure out if the difference is in the neck, pups, electronics, years made, i know nothing. If anyone has any info on the differences between these basses it would be greatly appreciated. And if I'm going to be getting scruff about asking about Gibsons, verbal lashing in a polite matter is preferred if it's not too much trouble. Thanks.
