I ordered this to replace the stock Tune-O-Matic bridge on my Les Paul Standard. I like a very low action but the fixed radius of the stock bridge prevents height adjustment for each individual string whereas the Babicz allows this, as well as for intonation of course. The whole bridge assembly is designed to be screwed down by the bridge posts so that its underside is in direct contact with the guitar body (as opposed to being raised up on height-adjustable posts) which, Babicz claim, provides improved tone and sustain.
Installation of the bridge was straightforward - following Babicz's youtube video (the printed instructions are insufficient) - except that the Allen keys supplied were slightly oversized and did not quite fit the screw heads, and the intonation screws were very tight initially but loosened after turning a few times. I suspect the plating process may have caused these problems - I used my own set of Allen keys to fit.
Once installed, adjustment was simple, the action is now as good as I could hope, and the feel and quality of the bridge is rock solid. Tone/sustain improvement - hard to say, probably slightly better, but it sounds great anyway. I am extremely pleased with the result overall - a great improvement on the stock bridge.
