alright so i bought a bass of of my friend a while back because i had to play bass in the band and since we all got together im back on guitar so my bass has been sitting on the stand i bought for it and the neck as like lifted the strings off the bridge and idk how to fix it i tightend down that bolt/rod that goes through the bass but im not sure what else to do.. i setup is decent and where i want it.
Picture would help, I don't get what you mean by the strings being lifted off the bridge is your neck bent or maybe you just need new strings?
how much did you tighten the rod at once?

you really, really, really shouldn't tighten it lots at once.

I can't really picture how the strings can be lifted off the bridge without the neck being off at a huge angle....
