I am trying to intonate my friends Ibanez Iceman but I've been having some problems. First, I should mention my intonation technique: I have been sounding an open note and then trying to match it to the 12th fret note by adjusting the saddles foreward or backward. (I have been using an electric tuner) I used this technique on my telecaster and it worked fine but on the Iceman the 12th fret note is significantly flatter no matter how close I move the saddles towards the pickups. I think this is happening because I need to move the whole bridge towards the pickups but it doesn't look like this can be done. Should I try raising or lowering the bridge?
I would greatly appreciate some help.
