Available at Angkor Music Melbourne, the Schaller Locking Machines 6 in Line Black – Lefty Reverse Headstock are premium locking guitar tuners engineered specifically for left-handed guitars with reverse headstock layouts. Designed to meet professional performance standards, these machine heads deliver exceptional tuning stability, precision, and long-term reliability.

The locking mechanism securely clamps the string at the tuner post, reducing slippage and eliminating excess string wraps. This allows for faster restringing, improved tuning accuracy, and greater stability during aggressive playing or tremolo use.

Finished in a durable Black coating, these tuners offer a clean, modern appearance while resisting wear and corrosion. The smooth, high-precision gear system provides accurate and consistent tuning adjustments, making them an ideal upgrade for professional musicians and serious players alike.

Built with Schaller’s renowned German engineering, these left-handed locking machines combine functionality, durability, and refined aesthetics for dependable performance on stage and in the studio.

 

Schaller Rear Locking Machines 6 in Line Black Chrome M6-135

 

• With this tuner the string is locked in the shaft by a handy knurled nut located on the rear of the peghead, resulting in a low overall height.

• 6-in-line models with two different shaft lengths (staggered).

• Gear ratio 1:16

• Schaller was the world's first manufacturer who developed the locking tuner and had it patented more than 20 years ago.

• Works like a traditional machine head, but the string needn't be "wound up" any more. Instead it is inserted into the cam hole with the clamp screw loosened, locked with the clamp screw and can then be tuned at once.

• This makes changing your strings a lot faster and easier.

• Only this patented locking system based on the ball socket principle prevents reliably from string notching and breakage.

• The string will not be wound onto the shaft any more. So it will stay in tune extremely well, perfect for non-locking tremolo systems.

• With all its benefits the Schaller locking tuner is the benchmark in the guitar sector.
