tube GT-KT88-SV med duet
EXCLUSIVE GT design. This is the highest-outputpower tube in the 6550/KT88 family, with special heat dissipation wings on the plate that let it reach the
same power specs as the original Gold Lion KT88 of the ’60s. The best, most durable and most powerful tone in the family, with outstanding dynamic response
and big bottom end. The definitive tube for bass amps, country, jazz, metal and any situation in which most of the tone shaping occurs in the preamp, pedals or
effects. Amazing high-horsepower delivery of clean tone.
