The 18w 1974X is a re-issue of the 1974 produced between 1966 and 1968.Just like the original, the 1974X is valve driven, hand soldered, with an aluminium chassis and has a tremolo circuit. Its two-channel design includes volume, tone, speed and sensitivity on channel one, the tremolo channel and volume and tone controls on channel two. The special 12″ Celestion G12M-20 Greenback in the 1974X has been ‘aged’ to get as close as possible to that vintage, worn in sound of the 1974.
