This 18 watt combo amp is a reissue of the classic 1974 produced from 1966 to 1968. Just like with the original, this combo is Tube Driven, Hand Wired with an aluminum chassis and Tremolo Circuit. The 12" Celestion Greenback has been "aged" for that vintage worn-in sound of the classic 1974. • MFSKU M-1974X-U • UPC 5030463148075
