Been away for work, just now got to see this thread again. Thanks for the replies.
Peromucho, just so I understand.. once its in tune, if the bridge is not level then I need to loosen or tighten the claw accordingly, but I need to adjust it FURTHER than I need to? That makes sense. Although I did try this and I found that I need to turn the screws considerably in order to get it to move. Like over one full rotation per screw. Does that sound normal? I'd not have expected it to need such a significant turn.
Doesn't matter how much turns in spring screws, you are aiming to correct bridge angle.
It will save you some time if you adjust bridge angle a bit further because no matter in which direction you correct bridge angle,
when tunning afterwards, tuning strings will always bring bridge back a bit.
LIke when you tuning locking bridge, FR or Ibanez or what ever, when you start tuning ,
to save some time, always tune string a bit higher,
because when you are tuning next string, previous wil go down in pitch..
and before tuning put fine tuning screws in midle position,
also when when locking nut,
locking pads wil usually turn a bit with allen key,
so you can predict that upper string, under pad, will after locking usually go up in pitch just a bit
and the other will go slightly down in pitch after locking.
With time and expirience, you can predict that,
so after you lock, string will be even closer to pitch,
and correct it after with fine tuners.
