The Grover Pro BDM-2A General Bass Drum Mallet features a 5/8" aluminum shaft that adds weight, giving you a punchier stroke and making it easier for you to activate the low fundamental overtones of a large concert bass drum head.
This mallet is made with a solid maple core covered in hand-sewn German felt. The core's oblong shape contacts more of the head than a round head will, providing additional richness and density to each stroke.
The General model is a great go-to size for most standard concert bass drum playing.
