Am I right in thinking that turning up the Kemper rig volume setting is not equivalent to turning up an amp's master vol and thus driving it's output tubes more without driving the preamp tubes more?
I ask because I find doing this and compensating for equal overall volume with the master vol control yields somewhat fatter tonality than just turning up the master volume does. Is it possible in a profile to adjust only the output tube drive contribution to the profile response?
