I bought one of these guitars as a project to pass the time while socially distancing (these guitars are absolutely awful, do not buy) https://www.gear4music.com/us/en/Guitar-and-Bass/SubZero-Generation-Electric-Guitar-Jet-Black/2C62
I have worked a lot on this guitar (replaced all the electronics and pickups, added a killswitch, replaced the hardware, sanded down the poly from a shiny and sticky finish to a smooth satin finish, changed the radius of the fretboard and replaced the frets with SS frets) but there is still one more problem. The guitar neck is slightly crooked and it causes the high E-string to be really close to the edge of the fretboard and keeps slipping off the edge of the fretboard. I have tried the trick of loosening the screws that connect the neck to the body and kinda gently forcing the neck to be straight (kinda like in this video https://www.youtube.com/watch?v=XJNrG2iqBO4).
The problem is that when I tighten back the screws it forces the neck back in to the original position in the neck pocket and the problem of high E-string being close to the fretboard edge still persists. I think the neck pocket itself is the right size, but it is crooked and I need to slightly widen the neck pocket.
The question is which side of the neck pocket should I widen and how? My instinct says that I need to widen the low E-string side of the neck pocket, because I want to be able to move the neck more to that direction. Is my instinct right? How should I do this? I do not have fancy tools, but I do have sandpaper/files/straight edges that I can attach sandpaper to etch.
