Designed at the request from Yamamotos pro-staff, the Yamamoto 7 Speed Senko was developed to be the ultimate worm for cover water. Molded with the same legendary Senko body shape but with the addition of a large hook shaped tail, the Yamamoto 7 Speed Senko produces a heavy thumping action that feels like a Colorado blade spinnerbait coming through the water, which triggers aggressive strikes and makes it easy for bass to find in dirty water. Perfect for weighted or weightless Texas-rig, the Yamamoto 7 Speed Senko is made for swimming through shallow water grass, laydowns, brush piles, and any other cover that bass like to hide in and ambush prey. Available in a wide selection of Yamamotos most popular colors, the Yamamoto 7 Speed Senko is a must-have for covering water and finding groups of active fish.
