Product Fundamentals
  • The Graph Tech PRB-5500-B0 Ratio machine heads offer an innovative way to precisely tune your 5-string bass. Each machine head is individually calibrated for the specific string, so one full turn of the knob changes exactly one tone. The closed construction protects the internal mechanisms and the Y-Style knob design ensures a comfortable grip during tuning. Perfect for bass guitar players seeking stability, precision and a sleek look in black. Suitable for left-sided 5-in-line basses.
