This ties into another thread where the OP asked how accurate to the original amps the Axe is. The AFD 100 is apparently so close no one can tell the difference between the sound of this amp vs the model (I sure can’t!), then it should not change in future updates. I am assuming the same is true for the other amps as well. Given the accuracy in v19, moving forward we may see optimizations, new amps and effects etc. but the sound should not change - this would be a great step forward and we can stop focusing on tone changes and look at features, effects and amps! Total win win!
