The Hammer Special Effect is the ultimate evolution of the iconic Effect, one of Hammer’s most successful high-performance balls in years. Featuring the powerful Huntsman core from the original Effect, this ball takes performance to the next level with the HK22-Cohesion Solid coverstock—one of the most dynamic covers in bowling. Finished with factory compound, the Special Effect delivers outstanding mid-lane motion and a bold, aggressive backend reaction. Compared to its predecessor, it offers the same effortless length but reads the lane slightly earlier, making it a game-changer when extra hook is needed on oily conditions. Built for versatility, the Special Effect is a must-have for bowlers looking for a strong, consistent reaction across various oil patterns.

The Hammer Effect Line is Complete!!!

The new Hammer Effect line is by far the newest and hottest ball line produced in years.  The Hammer Effect changed the game as to how pearlized balls can react in oil.  The Hammer Effect Tour took the original Hammer Effect and put a solid coverstock on it and created a new ball shape not seen from a solid bowling balls in recent years.  Now, Hammer has introduced the newest innovation in the Effect line, the Hammer Special Effect!  The new Special Effect has the successful new Huntsman core wrapped in the HK22-Cohesion solid coverstock with a factory compound which delivers an exceptional mid-lane motion and an aggressive change of direction off the spot.  The Special Effect compliments the original Hammer Effect by providing a cleaner ball motion through the front parts of the lane, with a stronger continuous ball motion through the pins with incredible hitting power.   I absolutely love the Hammer Special Effect and now I have all three Hammer Effect line balls in my bag, because of their versatility and predictability on both oily and medium lane conditions. Keep believing the hype about the Hammer Effect line because these balls are just simply amazing.  The new Hammer Special Effect in my opinion completes the Effect line and provides bowlers at all levels versatility on oily conditions unlike any other ball in the market today! The new Special Effect is available in your local pro shop!
