Grover Roto-Grip Locking Rotomatics Machineheads ~ 3+3 ~ Gold

SKU: 509G


3 treble and 3 bass, set of 6.

The Grover 509 Series Roto-Grip Locking Rotomatics, are the perfect choice for rapid and convenient string changing, whilst also a blessing for virtuoso vibrato guitar players.  

The rear thumbscrew mechanism locks and secures the string, eliminating multiple windings around the string post, for stable tuning, whilst ensuring accurate return to zero pitch even after the deepest vibrato bends.  

Constructed from stamped metal and with their distinctive 3-step button design, the Grover Roto-Grip Locking Rotomatic machine heads, feature precision engineered worm and gear components to eliminate string slippage.  

Roto-Grip Locking Rotomatics® utilise the famous 18:1 Rotomatic® design with a “thumb screw” mechanism that locks the string into place. Insert the string through the post hole, wrap around once, then lock by tightening with the thumbscrew. The housing itself is self-lubricating, for a lifetime of trouble-free service.

Perfect replacement for the most standard machine heads. Includes all mounting hardware.
