The Philip Kubicki Factor Bass is a brand of electric bass guitar made in America and sold factory-direct. Bass guitars designed by Kubicki are distinguished by a unique tuning module located in the body of the bass guitar rather than the headstock, as seen on most bass guitars today. The design criteria are based on human factors, or ergonomics, and the belief that a musical instrument should be inspirational to the player.
