What Stands Out
Electric Locking Mechanism
These tuning machine heads employ an electric locking system to ensure strings stay securely in place, providing maximum tuning stability and reliability for performing musicians.
Staggered Post Design
The staggered post arrangement enhances tuning precision and assists with string angle, resulting in improved sustain and a more resonant tone for 7-string guitars.
Chrome Finish
With a sleek chrome finish, these machine heads add a stylish touch to your guitar while offering durability and resistance against tarnish, ensuring long-lasting aesthetics and functionality.
