The Wards Airline GDR-9015A is a mid-1960s reverb-equipped tube combo from the Airline line, manufactured by Valco for sale through Montgomery Ward department stores. The GDR-9015A features two channels and spring reverb in a design that typifies Valco's approach to producing feature-rich amplifiers at accessible consumer prices.
