I have a Ibanez S7420 7-string with the ZR2 bridge and I think I just majorly screwed it up.
The guitar was set up for standard 7-string tuning (BEADGBE) and I set it to A# F A# D# G C D# (tuning up strings 6-2 and lowering the 1 and 7 a semitone) for 3 days and now my E-string (the high-pitched one) is touching the bridge pick-up. I know that to properly play in a new tuning I'd have to re-do the guitar's set up, but this tuning change was only to check it out temporarily.
Upon closer inspection of the whole guitar, it looks like the bridge got tilted side-ways due to the whacky increase in tension. I do remember the bridge making a springy "tick!" noise at one point during playing.
So my question is, should I attempt to straighten out the bridge again by adjusting the screws that control its height? I usually set up my own guitar, so I'm not exactly afraid to work on it, but I've never had to adjust this part of the bridge before and the manual says absolutely nothing about doing it either.
I've got an album of pictures with descriptions up here, any help is appreciated: https://i.stack.imgur.com/1KPWR.jpg
