So, I was setting the action intonation of all my guitars and such today, quite an enjoyable time. Some of you may or may not recall a red with gold hardware Series A bass I picked up recently. Its intonation wouldn't set, in fact the more I did the worse it got. Well, why wasn't it working? I'm not the sharpest bulb in the shed, but I think this may be an issue.

Not sure the pictures will work, but long story short is the bridge is giving up. I can see the start of a crack that will eventually completely detach. I do plan on changing all the hardware and guts on and in the bass so it isn't a big deal, it just means I won't really be playing it until I get replacement parts.

the picture isn't showing, not sure if i understand correctly what you meant, is the metal from the bridge bending due to string tension or is the bridge pulling up because the screws holes are widening / stripping..  

solution:
1 change/upgrade the bridge for better quality.
2 refill the screw holes and wait for it to dry completely then screw on the bridge.
I have Washburn guitars 'Maverick Series' and bass 'Bantam Series' and a few pedals and amps, but man I wish to have more patience and drive practicing my playing, if it's equal to the modding itch, then I'm golden.
