These are banjos i have been building out of maple, ash, and brass. Each will be different - as is all hand made objects.
Rock Maple, fretted or un-fretted, professionally made tuners, ebony or bone insets. (no fret board)
Steam bent ash (or other wood of choice), hand made tone ring of copper stainless or brass, hand made tensioners and head ring out of brass, professionally made head (or hand made raw hide).
they are beautiful to play, very responsive but with a well balanced mellowness. use either steel or nylon strings, and you will love its sound for years to come.
