A beefed-up version of Northfield Workshops F5 mandolin, the NFB-F5E Big Mon features a larger body size with larger f-holes for more mids, bigger bass, and increased overall volume. This model has a solid Engelmann spruce top and solid figured Northeastern red maple back, sides, and neck. These beautiful tonewoods are complemented by an impressive hybrid finish of hand-rubbed spirit varnish with a very thin lacquer topcoat for protection.
