Power up your game with the new Hammer Amp! The Amp features our new PowerShot asymmetric core, designed to provide ultra-high mid-lane revolutions with a very defined breakpoint. Combine that with our new Overdrive Hybrid coverstock, and you’ve got one of the strongest rolling upper-mid price balls in the history of Hammer. The Amp is finished with Powerhouse® Clean n’ Sheen to give this ball a smooth looking matte finish. Energize your pin action today, and throw more strikes with the new Hammer Amp!
