The Airline GVC-9064A is a late-1960s tube combo from Airline's GVC series, manufactured by Valco and representing one of the later models in the line before Valco's closure in 1968. The 9064A shares the raw, warm tone and tremolo features of its GVC siblings, with Valco's economic circuit providing naturally saturating tube performance. These later Airline models are increasingly collectible as interest in Valco-built instruments has grown among players and historians of American guitar gear.
