General

The Graph Tech PRB-4400-B0 Ratio Bass Machine Heads are high-quality tuning machines for 4-string bass guitars with left-mounted 4-in-Line configuration. Thanks to the innovative Ratio system, each string has its own gear ratio, making tuning more consistent and faster. One full turn of the key always provides a tone difference, regardless of the string. With Y-Style Contemporary knobs, a sleek black finish and durable sealed construction, this set combines ease of use with style. An ideal upgrade for those seeking precision and reliability.
