The Megabass FX Knuckle Squarebill Crankbait is an innovative shallow-diving crankbait featuring an adjustable square bill. Utilizing Megass’ advanced FX lip technology, the lip has two position settings that deliver different running depths and different actions. With the bill positioned up, the Knuckle dives a little deeper – down to 5-feet, and produces a wider wobbling action. With the bill tilted down, it runs a little shallower with at tighter wobble. The Knuckle also channels water between the lip and body in a sort of “water intake” system, which provides the bait with added stability so it doesn’t roll over at high speed like other square bills tend to do. Available in a range of proven Megabass colors, the Megabass FX Knuckle Square Bill Crankbait is as good as having two crankbaits tied on at once.
