All user reviews for the Grover Mini Locking Rotomatics

They released the same with a system that blocking any rope is fabulous.
But they look like the normal mcaniques (unlike Sperzel).
There's no better today (Schaller included).
It's simple and almost give juissif (almost, do not even when DCON)!

I own a Gibson SG and I was tired of mechanical vile green that break in less than two. I loved the shape of Rotomatic, so I have them installed on my guitar. I had the choice between normal and self-blocks, I took the car blocks, they do a good job!
You can play for hours without any detuning. I did a little test:
I played with my guitar many hours a day, and I had to wait three days to hear a false chord. The others were just detuned. I would do without hesitation that choice.
