General

Graph Tech PRB-4220-C0 Ratio tuning machines are specially designed for 4-string basses with a 2L/2R configuration. Thanks to the unique Ratio technology, each string gets its own transmission, making tuning more accurate and consistent. So you always achieve exactly one whole tone with one stroke, regardless of the string. The closed construction ensures durability, while the Y-Style knobs and chrome finish offer a modern look. With solid build quality and precise tuning, this is the perfect upgrade for any bass player who wants more stability and ease of tuning.
