Is it a newer used one or a older used one? Do you have the current active/passive set up or just the old school full time active version? The reason I ask is to find out what era of electronics are in it.
Generally speaking Carvin has a rather modern/hi-fi sound to their electronics, which I do like, but then again I also have a passive P-Bass Special so I do get the difference.
Just need a little more info, but I'm sure you will have plenty of peeps chiming in with their favorites.
