This model is one of my favorite bass amp models. According to the AmpliTube 3 manual, this amp is based on the "Fender Bassman." Okay, fine, but which one? There are more than a dozen different Fender "Bassman" amps. I have the certified '59 Bassman model, which is a 4 X 10 combo (presumably with a model of the 5F6-A preamp circuit from 1958-1960), and I think is still a 45-watt power amp (I don't think it's the reissue "LTD" model, because that's a two-channel amp). I also have the Bassman Pro 300 model, which is obviously a very different amplifier.
But the American Vintage B model has a 100-watt 6L6 power section model, which leads me to believe it's based on the 1972-1977 Bassman 100. Can anyone confirm this?
