D’Addario’s Auto-Trim Tuning Machines use precision locking tuner technology and a patented automatic trimming feature that cuts off excess string as you tune, removing the need for separate string cutters and keeping your headstock clean and snag-free. They also feature a precise, 18:1 gear ratio for smooth tuning and reliable tuning stability, while individual locking mechanisms keep the string in place at the post, eliminating the need for extra wraps that may cause unwanted slippage. That all means faster string changes, better tuning performance, and a pro-grade finish every time. We also offer Gold, Black, and Chrome options to match your guitar’s hardware, as well as 6-in-line or 3-3 headstock configurations. We even offer single units to accommodate extended range guitars.
