The black matte fretless carbon fiber overhead bass delivers the tone of an upright bass and the volume of a full-size acoustic bass, yet collapses to carry-on size of 22*14*9 inches! It assembles in 20 seconds with our patented detachable neck system, and our patented soundboard technology and all-carbon construction create a durable instrument with massive tone. Round wound PB strings, a 27 inch scale, best-in-class components, and a wedged ergonomic design make this the most enjoyable acoustic bass you’ll ever play! Tri-piezo pickup and a full-featured TSA compliant carry-on backpack included.
