I recently bought a Squer as a project bass which seems one hell of a bass for the money. Its neck is the only thing that seems to suffer from "cheap bass syndrome". It's a thin J-shaped neck which I can't seem to get straight. I tightened the truss rod all the way and there's still some concave bow left which causes buzz high up the neck. Does anyone have any advice for stubborn necks like this? I imagine using a higher string gauge would make the problem even worse? Thanks in advance.
