Fractal Audio Systems
I was mistaken. There is nothing wrong with the models. I had the controls set differently.Shows how important a community of 'beta testers' is to find issues, possibly subtle or difficult to reproduce ones that only a few notice or can find due to their setups.
Note, though, how the few that found the issue (now confirmed) were somewhat ostracized by those who couldn't hear it or replicate it. We are all in this (grand Axe experiment) together!
For a Fender the controls go 1-10. On the model they go 0 - 10. To replicate the amp's controls multiply by 1.1 and subtract 1.1. I had the amp set to 6, 6, 6 and set the model to 6, 6, 6 and there was too much bass and gain. But the correct value is 5.5, 5.5, 5.5.
