RedSeven Duality 100RSDuality 100 RS is the next take on our classic Duality100. Three independent channels of pure ears bliss. It share every single functions and the entire layout of his older brother but with an update power amp with 6L6s,an overall drier tone, means a little more high end focused distorted channels and with a slight more gain. Clean channel still the same of our Duality100, but of course with 6L6s on power amp. First channel, Clean is crystal clear,
