Less evident on the second example but is there...Are you using a treble booster or a bit shaper in the chain? What about Presence setting in the output menu and in the rig?
There are rigs that sounds like that, but I can always get rid of the buzz...Definition setting in the Amp block is a good one, Try reducing the distortion Sense in the input menu as well: I have a Schecter with EMG 70 and I had to go down at 2.1
Yeah its still there slightly but now i think its more just a frequency adjustment fix instead of a (probably all along) a hardware (guitar) issue that has plagued me all these years resulting in awful sounding high gain profiles. i think before the adjustment those little deadspots and slight fret buzz was making it a huge deal where as now i have pretty much removed all of those its really starting to come together.
So since doing those guitar adjustments i will now start to adjust the definition and distortion sense and see whats up.
Maybe now i can actually start dialing in tones #fingerscrossed
EDIT: No Treble Booster or Bit Shaper in the chain.
