FV1 (hard)
The perfect mallet for a big concert halls, and to play in an ensemble/orchestra. It's never too hard, but always articulated.
 
FV2 (medium)
The absolute allrounder. Suited for every kind of vibraphone playing whilst being able to enjoy an articulated sound.
 
FV3 (soft)
The warmest sound your vibraphone can produce. With this mallet you can play all the soft parts in your repertoire. It is also very nice to use it for the combination of vibraphone/marimba.
 
FV4 (two-tone)
The largest sound your vibraphone can produce. Enjoy the beautiful lushness in soft dynamics and strong articulation in the louder dynamics with this type of a two-tone mallet.
