Abstract: A detachable neck for a guitar allows guitar strings to remain in place and a lever action pivoting the neck to the body about a pivot point under the strings allows full string tension to be obtained. The neck joint attachment may be incorporated in new guitars or retrofitted to existing guitars. The attachment for detaching a guitar neck from a guitar body comprises anchor blocks, one attached to the neck, the other to the body, contact surfaces on the anchor blocks position the neck on the body, and a latch plate on the neck, spaced from the anchor blocks and a latch mechanism for attachment to the guitar body to fasten the latch plate and hold the guitar firmly to the guitar body with the contact surfaces engaged.
