Hammer Special Effect

Hammer Special Effect 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.

BALL IS DEFINITELY SPECIAL

Words can’t express how good the Hammer Special Effect really is. Hammer has really outdone themselves once again. I had the opportunity to drill two of them, one 60 x 5 x 30 and the other 40 x 4 ¼ x 70. I’m super impressed with the versatility, predictability and shape with both layouts. The HK22 Cohesion coverstock is devastating providing mid lane traction without sacrificing any backend motion. The Hammer Special Effect is a must have so visit your Local Pro Shop Operator and get your ASAP!!!

Perfect compliment to the Effect

The Hammer Special Effect perfect complement to the Hammer Effect. The HK22- Cohesion solid cover stock provides great mid lane traction without sacrificing super back end hook. This is due in part to the Huntsman asymmetrical core in the Special Effect. This ball will get down the lanes and make a strong arc into the pocket. I find this to be a great ball to switch to when a solid starts burning up or it can be a great choice out of the bag on the fresh. Either way, this ball has great ball motion and I strongly recommend it!

Hammer Special Effect

Last Tuesday, Hammer announced the 3rd release in the Effect line of bowling balls...the Special Effect. The Special Effect features the same asymmetric Huntsman core wrapped by a 4 color (purple/red/grape/black) cohesion solid cover with the known HK-22 base. I drilled one with a 60 x 4 3/4 x 30 layout and I went over the ball with a 4000 Siaair pad. (Box surface is 1500 Siaair/Factory Compound) I tried the Special Effect on fresh and leftover THS. Being honest, I never really used the original Effect a great deal. Between the Black Widow 3.0 and the original Theorem, I had an excellent range of motions in asymmetric core equipment. (Also there was one of my favorites as well, the Envy Tour for a much slower response on higher volumes for fresh. I also like the new Effect Tour for similar purposes) Additionally, I had a little trouble getting the original Effect to match up with my game. I did use a little weaker MB and pin placement to see if I could get a better look. (The original Effect had a 40 x 4 1/4 x 25 layout) I can already tell I am going to like the new Special Effect more. They are similar and from what I can see in terms of watching them from shot to shot, they are pretty similar. That being said, I used it in league and what I noticed is that the Special Effect got around the corner better in the last game when I had to use a very steep angle through the front. I don't know if it's cover or layout but I do like the motion of the Special Effect better. I do see the new Special Effect being in my bag and I'll be looking forward to drilling a second one shortly. The Hammer Special Effect releases officially today, March 20, 2025. See your local pro shop for more information!

The Hammer Special Effect is Special

The Hammer Special Effect is just that a special blend of the original Huntsman Core and the HK22 Cohesion Solid and finished with the Factory Compound has smoothened out the reaction of the Original Effect yet provides awesome recovery and hitting power. This ball is Good! This balls allows me to play up the boards as well as move to play inside angles. Even when there is some oil on the lanes you can see this ball tracking through it and still providing the hitting power and motion on the backend. This is a great addition with the Effect Tour and Original Effect. You can see the progression from the Special Effect to the Original Effect when the lanes begin to break down. The Effect Series is providing great reaction and reliability.
