An instant access guitar system allowing easy access to cavities in the body portion of the electric guitar. The cavities are covered by plates, a pick guard, flexible laminates or other suitable cover materials. The covers are held in place by magnets that magnetically attach to magnetic material mounted in the guitar body. The appearance of the guitar may be changed by changing the pick guard and the decorative laminate on the headstock. The sound of the guitar may be changed by having unique pickups and wiring releases pre-built in multiple configurations on multiple pick guards as modules to change in and out of the guitar at will with no tools or solder.
