Have you tried this? https://tonelib.net/forums/threads/pantera-vulgar.8294/ I used that patch as inspiration to my guitar tone and distortion, I'll upload it here when I have the time to. But what I noticed is that using the filter Gt GEQ 7 and other filters helps A LOT when you want a specific tone in your guitar, you just have to be a little patient to find the perfect tone for you.
