Bridge design on Ibanez GWB35?

Hi all,

Just today I went out and purchased a used Ibanez GWB35. :D According to the seller it is from 2007 (Serial# C 06111438) and is practically unused. It does look mint condition and I can't see any wear what-so-ever.

The bass need a good setup though, so I prepared for that, and while doing so I noticed something I have never seen before on any bridge, so I am curious if this is a defect on this particular bridge, or if it is really supposed to be like this. You see how the rear end of the bridge sort of lifts from the body - is this really how it's designed?:

After reading about this hiked-up bridge problem, I observed the same condition on my GWB 35. Not cool. Things need to be flat and in full contact at all points in my view. This is clearly a factory boo-boo that was not caught or ignored by Quality control.
Problem: When the five lower mounting holes were drilled and counter-sunk (probably on an automatic machining center), too much downward pressure was exerted and the plate, weakened somewhat by the drilling of this line of holes, bent slightly along this line. hold it up for an end view and you'll see that the "kink" follows this line)
Solution: this can be gently straightened/made flat again if done carefully and correctly.
I did mine and it's fine now. Do not smack it with a hammer.
If anyone wants help with this, let me know. I will check back in a day or so

Definitely a defect. It almost looks like the string tension has pulled & deformed the bridge. Hopefully it's just a crappy bridge, b/c I can't imagine any guitar being allowed to leave the factory like that. I would pass on it unless you're getting such a great deal or love the bass so much that you can justify the cost of a new bridge on top of the price of the bass.

it is a defect, caused by the drilling of the bridge during mfg.
Pretty sure string tension would never be enough to bend that plate, but getting greedy with drilling machine pressure at the factory will (and in the case of my instrument ,did) cause the bridge to hike up along this line.
I was able to gently bring it nice and flat again and reinstall.
