alright, so I've decided to change the string gauge from .10s to .9s (D'Addario), and still, the strings tension is still almost as tight as with .10s strings. I don't see much difference. I don't understand, because long before my strings were easy to bend and they seems a bit loosen. I was able to bend the strings easily in tune without having to use so much force that kills my fingers so fast. And I tried other guitars in the shop when I went to buy the strings, other guitars were much easier to bend and not so tight like mine now. However, I didn't have this problem with my guitar until I had my pickup change to Lindy Fralin Blues Special and the tech might have done some change with the setup, perhaps it's the neck relief or truss rod or... idk. After that the tension becomes super tight, it just doesn't seem normal... I mean, I've been playing for a while already, "I used to be able to bend in tune"... but now, it just becomes so tight I don't know what happened. Even changing back to .9 doesn't seems to help much.
