I recently changed the strings on my Ibanez GIO GRG170DX and I noticed that after tuning the guitar, the bridge was lifting up (no longer flat with the body). I don't think it was like this before restringing, but I can't figure out what to do to fix it.
I watched a youtube video which recommended that I loosen the screws on the front of the bridge, but when I did that it didn't really seem to help.
How can I prevent my synchronized tremolo bridge from lifting?
