Designed in collaboration with percussionist and educator Ian Grom, the Vic Firth M262 Corpsmaster Keyboard Mallets deliver a versatile medium response with the projection and clarity needed for modern front ensemble performance. The Ian Grom Signature Series is built for demanding marching and concert applications, offering a balanced feel and consistent response across the marimba. The M262 is an excellent all-purpose choice for players who need a clear attack while maintaining a full, musical marimba tone.
