I had contact problem with my pots in my Epiphone Les Paul.
As I had a good experience earlier with Goldo pots using them for my Stratocaster so I was brave enough to order them again.
Very good quality pots, not too easy too rotate but not too stiff either...just perfect, exactly what I like.
Soldering them is literally a dreamjob, no problem whatsoever.
The contact problem is now gone, sounds perfect!
(it's Japanese so it's not a surprise to me at all why it's so great)
I can only recommend them to anyone, especially if you compare its quality to their price.
I will buy them next time definitely.
