The NRP Steel features a steel body but instead of the painted finish of the “B” Series instruments, it boasts a rubbed nickel exterior that gives the guitar a deep, lovely sheen. Just like the original 1930s Nationals, it has flat-cut f-holes and a ribbed sieve-hole resonator coverplate. The Honduran mahogany neck with truss rod is topped by an ebony fingerboard and slotted headstock. And like the B Series NRP guitars, the tone is incomparable, echoing the tone of a vintage National.
