I'm going back to bassics, all four strings for me. I'm getting rid of my Sadowsky MV5, and getting a new Music Man Stingray HS 4 string. I'm also going to be putting in an order for a fretless Stingray HS 4. I've decided that 4's are the way to go, at least for me. Have any of you guys gone and completely revamped your bass collection to be only 4's, 5's, or 6's? Just curious.
