newb needs help

hey, im new to the forums and playing bass, i played guitar for about a year than decided to make the switch to bass, a few days ago i bought my first one, an olp MM2, its prettyn sick but after a day or 2 i experienced some fret buzz around the second fret of every string so i took of the strings and were attempting to put them back on but my bass is very different from my guitar in the way the strings turn to tune so when i put the strings back on i must have screwed something up because now when i play the strings open there is an extreme buzz and you can't even hear the note so i need help on how to properly put bass strings on the right way, my guitar is the olp mm2, so if anyone has the bass or knows how to put the strings on properly i could really use your help.

 

thanks alot man

 

i looked at my bass after taking a look at that site and i don't think my guitar has a truss rod, they're is this wheel type this where the neck meets the pick guard but i cant find an alan key hole anywhere
