I had troubles with my Gibson Les Paul Standard Plus 2014 tuning stability and scale length adjustment. The guitar equipped with locking tuners, but even then I was forced to fine tune the guitar every 2 songs, that is quite annoying. First step I did - I replaced the nut to Graph Tech GT PT 6010 00 Black Tusq XL. It was helpful, but not enough. So I decided to try ABM Rollerbridge.
Pros:
- almost zero friction,
- much wider scale tuning space (about +30%). I finally managed to perfectly tune the scale length on every string
- extremely precise and well built construction, it looks more like an aircraft part,
- easy to install.
Cons:
- too pricy, but in view of the quality, it worth it. I didn't regret the purchase at all.
I would highly recommend the item to everyone who has the same problems.
