Cases for the protection of stringed musical instruments having a bottom, a sidewall of a predetermined height extending from the bottom and a cover which is hingedly connected to the sidewall and which can be closed and secured with an appropriate fastener are described herein. The cases include a semi-rigid neck-brace having a height approximately the same as the inner height of the sidewall and being affixed to the bottom. The cases further include at least one retaining band that may be used to releasably secure the instrument neck to the neck-brace. Instrument damage may be prevented in the event of a sideways or backward fall, in at least part, because the neck-brace suspends the headstock between the bottom, sidewall and cover of the case and thereby prevents it from making contact.
