I had my dad's bass guitar lying around (I play with it, but don't play it, if you know what I mean - I'm a drummer myself). I believe that it is a Stagg B300-SB Standard J. It had been lying unused for a while and I saw that the strings were very rusty. I am not sure whether that is actually a sign that they need to be replaced, but I like to take things apart to learn how they work (bad habit, I know).
So I bought a new set of strings (Elixir 14052 Electric Bass NPS Nanoweb Light 45-100) and put them on following a tutorial online. The thing is that I took apart the bridge, to clean the parts, and then put it back together. But I think that I messed up the order or did something else wrong. The reason why I think that, is because the strings are not at the same height and the bridge looks... wrong. Please see the attached pictures.
I could not find a guide to re-string with this kind of brdige, so any advice on this is helpful. I guess I have to screw in the "legs" to make sure that they are all the same height? Or is there something else I should do? Should all these things be at the same distance from the butt of the guitar, or should they in fact be a bit apart?
