A 0.750” thick all aluminum bass guitar using a neck-though-body design, integrated bridge, with ambidextrous playability at its core. By using an elliptical neck section, and removable fretboard we have lightened the instrument by over 25% the weight of the initial prototype; while chamfered faces on the body and ‘longhorns’ ensure a center of gravity perfect for playing strapped and standing or seated. The mass of the aluminum body along with the rigidity of the aluminum neck provide maximal frequency response and sustain.
