The Megabass Vibration X-Ultra is unmatched in its class, with a realistic bluegill/shad profile that provides the angler with a clear edge over any competitive model. While the profile of the Vibration-X Ultra will visually trigger bass into slamming this lure, the real key to its fish-catching ability lies in its revolutionary approach to design: instead of relying on the shape of the head to produce the desired action through the movement of water on and around the lure, the Vibration-X utilizes internal balancers. This system focuses on the tension between balance/imbalance as the driving force behind the tight action necessary to create vibration, resulting in a lure that never fails to deliver. This design allows the Vibration-X Ultra to be fished at any speed while producing a tight vibration that will generate strikes from both aggressive and non-aggressive bass.
