A Tone Cut control for the Top Boost model would really complete the profile. On a Vox AC15/30, the interaction of the harmonic distortion from the preamp section with the later control of higher frequencies in the power section is an essential feature and sound of those amps. Since the Vox AC15/30 tone stack has a fixed mid value, the Middle tone control on the Atomic could be used instead as the Tone Cut control, when the Top Boost model is activated. (This is how Fractal and Iridium have also implemented their models of the Vox AC15/30.) I use my Firebox as a direct replacement for an amp. In the heat of battle, it's useful to make adjustments on the fly using the existing knobs, and not have to connect a PC and then somehow approximate the tone cut using EQ. Also, it would be great to have a model of the Normal channel on a Vox AC15/30.
