Provided is a modular string instrument including a core string instrument and interchangeable instrument body types. The core including: a core shell forming a basic shape of the core string instrument, a string instrument head, a neck base, a chassis assembly configured to be inserted into the core shell, extending from the head to the neck base and comprising a strings anchoring bridge, a plastic fret board configured to have frets attached thereon, the fret board configured to cover the core shell and to encase the chassis assembly within the core shell, a neck base cover configured to be attached to the neck base, a pickup cassette bay configured to encase an interchangeable pickup cassette, and strings stretched from the bridge over the pickup cassette bay, over the neck base to the head.

Interchangeable neck and bridge components for a guitar. The body of the guitar has a recess having two parallel side walls and a sloped wall. The sloped wall is located between the two parallel side walls. The recess has a bore configured to receive a fastener. The guitar has a removable neck having a fretboard. The fretboard has a primary side located opposite a secondary side. At least one string is located on the primary side of the fretboard. The removable neck of the guitar has an end having a capturing structure connected to the secondary side of the fretboard. The capturing structure has a guide ramp. The neck of the guitar is secured to the body of the guitar when the bore of the recess of the body of the guitar and the bore of the capturing structure receives the fastener.

Modular stringed instruments are discussed herein. The modular stringed instruments allow users to more efficiently transport the stringed instrument, replace broken parts, or personalize or customize the stringed instrument. They include a bracket, a neck, and a headstock. The neck and the headstock are separate pieces which are adjoined together, such as by the bracket and a connector bolt, and can be separated from each other when it is desirous or necessary to do so. The bracket opposes or resists forces caused by the strings of the stringed instrument when the strings are placed under tension and extend from a body, such as from a bridge of the body, to the headstock.

A stringed instrument, for example an electric guitar, comprises a neck and a body defining a neck and body joint. The neck and body joint includes a neck having a tapered tenon, and a body having a complementary tapered mortise surrounding the tapered tenon. The tapered tenon may be held within the tapered mortise with a tensioning device without the use of adhesives between surfaces of the tapered tenon and surfaces of the tapered mortise.

A foldable stringed instrument, for example in the form of a travel guitar that folds mid-neck to assume a reduced profile is described. The mid-neck folding is accomplished in a symmetrical manner about a three-part hinge located in the neck to configure the travel guitar into a reduced profile. The bridge assembly can be translated longitudinally relative to the head of the guitar to allow sufficient detensioning of the guitar strings to enable an upper portion of the neck to be folded away from a lower portion of the neck and/or body to assume a reduced profile. To deploy the travel guitar for playing, the upper portion of the neck is unfolded into alignment with the lower portion of the neck and/or body, and the bridge assembly translated longitudinally relative to the head and locked in position to allow the guitar to be tuned for playing.

An adjustable neck joint for a stringed instrument includes a neck with a heel portion formed as a first half of a rotating joint and a body with a neck block formed as a second half of the rotating joint. The first half of the rotating joint and the second half of the rotating joint may each be configured to connect with the other and movably interface with each other such that the neck is rotatable with respect to the body about an axis located immediately adjacent to and above a position along the neck.
