Super locking tuners

thecoverguitarist 10.08.2025

I got this tuners to upgrade my cheap harley benton multiscale guitar
And now it plays like a dream
It stays now great in tune not like before with the stock tuners
The quality difference between the oem tuners and this is miles apart
The guitar is also easier and faster to tune because of the ratio tuners and the different gear sizes it has per string
