What if the amp doesn't have a gain knob. My Bassman, AC30, DR, and Marshall, don't have a "Gain" knob. They have volume knobs. I like turning up the "Volume" to overdrive those amps. My Bassman sounds amazing cranked up. The amp goes crazy, It sags more, the louder you crank it up. That's what I would want. I don't like fake gain that acts like a distortion pedal. Is that what it's going to do? I don't know how, because of the way all of the components and speakers react to the volume change is part of it. That would be awesome.
Nothing can be all things to all people. I would expect a liquid profile to be closer out of the box. With controls like Definition, tube shape, power sagging, compression (amp), clarity....... you'll probably get there. I preach my love for the back-end control on the Profiler all the time, but I know of no other digital solution that gives you this sort of fine control over a sound.
