Guitars and basses: protect the headstock and neck without forcing them

The headstock is one of the areas that can receive high stress if the instrument moves inside the case or the parcel takes an impact.

Immobilise the body and support the neck over a sensible area, leaving clearance around protruding parts. Do not allow accessories, tremolo arms, tools or power supplies to strike the headstock or finish.

Do not make extreme changes to string tension purely for shipping without a technical reason; follow any specific manufacturer or qualified technician guidance you have.
