I have a 2023 Squire Affinity Strat that I am setting up for my daughter. I cannot get the trem to return to pitch no matter what I do. The nut is cut correctly and lubed. The tree and saddles are also lubed. When I do a dive bomb it will not return to pitch but if I give the strings a tug it goes back in tune. I have the Trem decked as that is what she wants.. It is getting really frustrating. Does anyone have any ideas or any advice? Thank you.
