Strobel Guitars make proper playable electric travel guitars that fit into a laptop sized briefcase. These are real gigable guitars that can be packed in your carry on luggage! After experimenting with several prototypes Russ Strobel built the first Rambler Custom travel electric guitar in 2003.  Since then two more portable Rambler models have been added as well as a bass.  Strobel offer both US made and Korean made models to fit your budget.
