The 5AB spec, which is the standard for drum sticks and is positioned between 5A and 5B, has been revived in various finishes in the Rebound series. The inspiration for this project was the Larnell Lewis Signature Fire Grain model, which was released last year and received positive reviews.The specifications have been fine-tuned to reflect his requests and have been incorporated into this new regular model. The grip thickness is .580/approximately 14.7mm, which is between 5A (.565/approximately 14.4mm) and 5B (.595/approximately 15.1mm), and has been added to the American Hickory & Long, Active Grip, and Fire Grain lineups. The center of gravity is closer to the grip, and the weight at the tip is light, resulting in a light sound. ActiveGrip The heat-activated grip is also effective against slippage caused by sweat, eliminating the need for extra force to prevent slippage and helping to relax the palm of the hand, improving control of the stick. The specially painted active grip uses the latest technology from D'ADDARIO, which has even included a chemist on its production team. This product is different from conventional colored sticks or rubber coatings, and does not transfer color to drums or cymbals.
