You'll need to give us some more information here. What's the trem angle like, what is your action (in mm at the 1st, 7th, 12th and 24th frets) what gauge strings are you using, how many trem springs are in the guitar. Is there any forward or back bow in the neck or is it dead flat.
These guitars are pretty tricky to get set up until you learn some tricks and get used to doing it. I REALLY suggest that you learn to do it yourself. Only you know how you want your guitars set up, so you're the best one to do it right. Plus it's much cheaper and saves time.
So go to the guitars section of the main jemsite website and click on the setup section. The guitars being set up in that section are Jems but it's same same. If you walk through that step by step you should be fine. It takes a long time at first, so don't start at mid-night, and be very patient with yourself. Your fighting tensions all over the guitar and each little move in one area causes a reaction somewhere else....it's tricky to get in balance. But once you do, it's pretty much done.
Also check out Rich's tutorial at ibanezrules.com (banner above). He's got a great area dedicated to cleaning and set up.
I will caution you in one area though. Rich's advice on trem removal for neck adjustments (shimming the neck pocket) is great and I do it all the time, however I would caution against that with the piezo trem unless you are exceedingly careful.
I like the bottle cap method for maintaining pressure on the trem and I think Rich has that one on his site as well. He takes two 2-liter sized plastic screw on caps and a decently thick piece of something with some padding to it and uses that to keep the trem from dropping down inside the cavity due to lack of string pull (cuz the strings are off the guitar). This works like a charm.
If you really get fed up with it, just PM me and I'll see if I can be of more help...although it's tough without having the guitar in front of me. Another option is to just let me know and I'll buy that sucker off of you and rid you of your problems.
