Unlike other electric upright bass models with a solid body, the Eminence Portable Upright Bass is a real acoustic instrument. It's smaller and more compact than a standard-size acoustic upright bass. But: the acoustic body has an arched top and bottom, a bass bar and a soundpost - the same structural design as a standard-size double bass. That's why the Eminence sounds and plays like your standard-size double bass, and not just like fretless bass guitar. The unamplified sound of the Eminence is great for practicing in the hotel room or if you have sensitive neighbors. Played amplified, the Eminence with its acoustic body sounds like a larger acoustic double bass. The Eminence has a detachable waist extension, and an anti-rotational endpin, the Steady-Foot. That's why it stays very easy in playing position. The string length of 105 cm (= 41-1/4") and a standard-size neck deliver a familiar playing feel and an easy transition from standard-size double bass to portable upright bass.
