I might be getting a Johnson bass free from a friend but the neck is in terrible condition. Looking around people have usually put J necks on these P basses and have said it almost fits but has a small gap. If I am correct, P necks and J necks have the same width at the pocket, so both would end up with a small gap. I was planning on ordering a neck from warmoth, does anyone know what the specs should be for the neck to fit snug?
