I am still a fan of using https://ignition4.customsforge.com/
The tabs are “hidden” in the Rocksmith song format, but you can either convert it to GuitarPro using Tonelib Jam or (the more complicated) Rocksmith Custom Song Toolkit (https://www.rscustom.net/).
The quality can be hit & miss, but I would say that it’s better than most Songster tabs I have encountered!
