UniValve Amplifier
The UniValve is a 15-watt amplifier head released in 2001. Although it operates with only one output tube, it was designed to take a wide range of output tubes without needing to be rebiased. The UniValve was the first-ever recipient of Guitarist Magazine’s “Guitarist Gold” award, under their revised scoring standards. The etched design on the amplifier’s front panel was made to resemble the work of artists and architects Charles Rennie Mackintosh and Frank Lloyd Wright. As of 2004, only around 1,300 UniValves had been produced. Their serial numbers start with 000, although model number 000 was given to the THD dealer who coined the amplifier’s name. Billy Gibbons (of the band ZZ Top) requested serial number 007, and model 666 (which is written on the back of the UniValve chassis in red ink) is owned by a former THD employee.
