Upgrading the potentiometers in any guitar can have big influence on sound (by my experiences and ear). Using quality potentiometers is essential or much desired.
TAD products are now well known for their quality and consistency, since they take a bit more detailed QC.
Those CTS potentiometers made for TAD are of great built and quality. They will last and upgrade the sound of any LP style guitar where they are used.
The friction of the potentiometer is in the middle range. Not soft and not hard. But it's leaning towards soft friction.
