In 1994 I played a Dual Rectifier (don't know the revision) and it was the only amp I've ever heard that sounded exactly like a broken in 1968 Marshall Plexi 100 head and cab, but it didn't do cleans while a Marshall does just by changing your pick attack.
Rev C maybe. It’s been described as the brightest of the early 2ch rectifiers (and having the worst clean channel). Mine is a 2 channel from the 90s also and it’s also one of ny favourite amps. Incredibly versatile.
