I recently installed this bridge on my Fernandes. The construction and locking features are really helpful. The only downside to this bridge is that the saddle only moves a very short distance. This can make setting intonation a pain. Especially on the B. I had to switch to a tapered B to get the intonation right. However the bridge is very well made and adds a lot of sustain and mass. Not to mention it looks very cool and unique!

Love this thing. I've had in on my flagship bass (an Ibanez GSR-205) for well over a year of gigging nearly every weekend. Intonation never slips. Easy to set up as well. Strangely, the satin finish on the bridge and the satin finish of the O-ring knobs do not match when you look closely. Oh well. Side note, if you're upgrading a GSR like mine, the .708 string spacing is a bit wider than that bass originally comes with, but it fits on the fretboard just fine, and I actually very much prefer it. Narrow, fast neck with a little extra space. I offset it toward the B-string side just slightly so as to give me a little more room on the G-string side where I actually use those upper frets, though the B-string is still sitting comfortably over the 22nd fret.

I put this bridge on a 5 string Jazz bass I refinished and its the best purchase I could have made. It took a little time to figure out how exactly to set the tonation but after that was done I haven't had to touch it since. I love the mass of this bridge and coupled with the string through I can play a note walk away for a while and come back and it would still be ringing out. This bridge gets a 10 in my book!
