Graph Tech Introduces Bass RATIO “Total Control” Machine Heads for Left-Handed Players

Graph Tech has added a new set of tuners to their popular RATIO Total Control Machine Heads designed specifically for left-handed bassists. Available in 2+2 or 4-in-line configurations, the new set is made to fit left-handed basses.
“We understand the challenges left-handed bass players face in finding equipment that meets their specific requirements,” says Graph Tech founder Dave Dunwoodie. “With our new RATIO Total Control Machine Heads for Lefties, we’re proud to offer a solution that combines unparalleled precision speed in tuning your bass.”
The RATIO tuners were introduced to basses five years ago. They feature balanced-gear tuning technology, meaning each string has its own calibrated gear ratio. “From the Low E to G string, ratios range from 36:1, 30:1, 20:1, to 18:1, ensuring consistent and precise tuning across every string,” Graph Tech writes.
The Graph Tech RATIO lefty bass tuners are available now for $114.99.
