Does this mean that the model's gain structure is going to change significantly, or are we going to end up with the original models and some new ones? The 'Jumped' version is my favorite.
I doubt it. You can emulate the Low Gain input by reducing the Input Trim control. For that reason all the models with high/low inputs are modelled with the High Gain input. He was just using the wrong one so seeing less gain that he expected on the amp when verifying.
