The person who ordered this banjo requested a "patchwork quilt" effect for the rim. There are 8 different woods used: maple, mahogany, walnut, cherry, bloodwood, purpleheart, bubinga and good ol' oak. With a dyed calfskin tacked on, it turned out beautifully.
The neck is a distinctive piece of walnut, with a bloodwood fretboard.
The banjo is explained and demonstrated in the video below, followed by more photos of the banjo.
