The Encore NZ5B Nancy Zeltsman "Medium Soft" mallets are a nice, articulate bass mallet. They produce a very warm sound that can also be used in soft graduated sets in the "tenor" position. Birch Handles.
 
One unique characteristic of my line is that the oval-shape of the mallet head is horizontal rather than vertical. I imagine (and maybe it's true) that the width of the mallet activates more of the vertical grains of wood in every bar-thus contributing to a richer tone. Everything about the construction of my line of mallets-from the cores, to the latex, to the type of yarn-is aimed at helping you to produce a fundamental-rich tone.
