The neck is tuned to pitch, relief is measured about the middle of the fretboard, as well as the motion is played throughout many frets. Should the relief has moved only somewhat, the neck might require no adjustment in any way. If the middle from the neck is just too straight or way too ahead, a little truss rod correction delivers it again towards the player's preferred selection. The same Examine is repeated when heating time begins or any time a humid summer months comes.
