Factory Models
At the turn of the decade the Di Giorgio company made many changes on the factory floor. Some models of the 1960s were discontinued with new models created. Pau Ferro began to be used in Back & Sides as replacement for Jacarandá and Tops were manufactured thicker.
The Di Giorgio guitars of the 1970s were exported around the world and it is common to find factory models available for sale in many countries today.
