I installed this bridge on a custom made hardtail ST guitar.
I really liked the idea of having adjustable position for the strings in the bridge.
The locking feature provides a plus of stability over time, which I found a design plus.
Design issues:
Unfortunately, the string adjustment is not working really as advertised: when the roller is adjusted to an extreme position, the string makes a relatively strong knick and teds to jump out of the saddle groove.
Also, there are positions where the string comes in contact with the saddle body and this causes obvious buzzing. The buzzing is not picked up by the magnetic pickups, but it is there, and very annoying.
QC issues:
I had 4 saddle height adjustment screws that were not cut correctly. They were EXTREMELY hard to adjust and needed some re-cutting of the threads.
Overall:
Leaving the aforementioned issues to the side, this is an extremely versatile bridge, fitting a broad range of guitars and needs, especially because it comes with an extra height adjustment plate. The string position adjustment is great when trying to align the strings with the pickup poles on non-standard string spacing.
