There were no changes to the modeling.Something is 'off' between 17.01 & 17.02 to my ears. I'm hearing a bit more fuzz or hair in all of my distorted tones. Previously, it felt organic. Now it sort of sounds digital to my ears. I'm gonna dig in to see if it's the Master volume or where the tweak to dial it out is. I haven't seen anyone else post the same thing so it's unique to me.
Edit: A high cut and a little smoothing in the CAB blocks dialed it out. Also, adding a tad more speaker drive helped. I didn't touch the Master though.....maybe I should.
