From Journey:

"Patented removable neck system allows this acoustic travel guitar to collapse into an airline carry-on size case for the traveling musician or backpacker. The Overhead carries a clear resonant tone with surprising volume and bass. The relatively small body size is able to carry a full sound through the use of a Manzer wedge which increases the air volume while keeping the top of the guitar close to the body for comfort. Also includes tone-enhancing premium-grade bone nut and saddle, along with ebony bridge pins.

Soundboard: Solid Sitka Spruce satin finish
Back & Sides: Sapele satin finish
Case: Custom-designed travel guitar backpack engineered to fit in airline carry-on compartment (see specs here)
Pickup: Proprietary under-bridge transducer pickup system
