The GA-70 was introduced to the Gallagher collection in 1998.  This grand auditorium model features a rosewood back and side with a select sitka spruce top. It has appointments like all of the 70 series guitars: ivoroid bound body, neck and fingerboard; mother-of-pearl diamond and square position markers; ebony fingerboard and bridge; herringbone purfling and sound hole rosette; bone nut and saddle; and chrome Schaller tuning keys. The neck width at the nut is 1 3/4".  The grand auditorium body provides the balance desired in a fine finger style guitar with a stronger presence than the auditorium body style.
