Hey Sixstring,
i only skimmed over the thread but had a lot of tuning issues with my Ibanez Jem and feel your pain. It was exhausting to try and get it to work properly with an edge trem and locking nut. All this to say that in my case it was the a trem spring causing the issue. The loop on the low end spring was starting to open up and it was the source of all the heartache. Also some of the trem spring lengths may be different (some shorter than others). Just a quick spring swap and it seemed to take care of the issue for me
Even if it's not the issue it's worth the investigation just to cross it off the list : )
