The bridge on the axe banjo is made from black walnut. Again here is the black walnut info for the tree hugger in all of us. The black walnut was not harvested from a living tree. The walnut tree had fallen on my property, possibly in a storm, and I had harvested the fallen tree for firewood. I scavenged one of the sticks of wood to make the bridge from.
Also I spaced the strings at 0.5”. Traditionally the strings are at about 0.375” to 0.425”. This is done just for me. I have fatter fingers and for me, this small spacing difference makes the banjo easier to play. I understand that Gold Tone also has models with wider string spacing for people like me.
