Thanks guys.
I gave it some more thoughts and checked again, maybe it's not the trem fault itself …
The bridge as mentioned is an original made in Germany Schaller floyed and the problem is that it's hard a as rock when trying to bend and also gets out of tune when bending, it's not sensitive enough.
The knife edge is one option but I suspect maybe it is only a setup problem after all, the bridge in my guitar is not 100% sank inside its cavity, its above it, you can see in the pic:
I can't take it further down as the strings will hit the frets.
Anyway I will probably try to take it to my guitar tech prior of spending 250-300$ on a new bridge.
The Edge pro of Ibanez IS a very good bridge, I have an Ibanez Prestige loaded with that guy and the feel / balance is perfect.
I had here for some time a cheap Mexican Charvel San Dimas Pro Mod loaded with a floyed rose which I suspect is made in Korea but the bridge was 100% in its cavity, I can only say good things about this guitar, it's so soft / smooth, so sensitive and so fun to play, it never gets out of tune and I can do very fast vibrating (hitting the arm fast and release) and it does the job perfect
Ill update here later.
Thanks.
