Help please. I just started playing bass about a month ago, and before I left the guitar to go home for 2 weeks, it occured to me for some reason to loosen the strings a bit. I gave each of the strings probably about 2 rotations just to ease the tension a bit. I got back the other day and tried tightening them back up, but now the entire setup seems to be off. The strings are either awfully loose (if tuned) or the strings touch the top 4+ frets. What should I do? This is on a SX P bass btw. Also, are my strings suppose to be centered between the dots on the pickupts? Some of them are off, I think the things that guide the strings have shifted on the bridge. TIA!
