A portable travel guitar that can be quickly disassembled to fit in a business briefcase. A string keeper disengages from the end of the neck and maintains the strings in order when disassembled. This feature allows the neck to be separated from the body for compact storage when disassembled. The body includes string storage flanges for stowing the strings that are wound around the storage flanges. The portable travel guitar is assembled by unwrapping the strings from the storage flanges, setting the neck in place, and attaching to the body with bolts and wing nuts. The string keeper is set into place at the top of the neck and attached with thumbscrews or other appropriate attachment method. The guitar is then tuned as normal. The assembly and/or disassembly process takes about five minutes and requires no tools.
