The pictured bridges are two different versions. The one you will receive is the one with the screws on the "front" side which are retained by tiny nuts on the rear side. When the saddles are adjusted to the rearward extreme, loctite from the nut gets into the saddle, causing it to bind. At this point you can either not adjust your intonation, risk melting the tiny nylon washers getting it hot enough to overcome the loctite, or strip your screws/shear the heads off of them. This is a terrible product. A lot of money for a cheap Gotoh bridge with two threaded holes and some set screws.
