So I tried to higher the action on my Aria bass, it had really low action when I bought it. And while heightening the high G it broke, and this was before the string was at even medium height action:S I must admit this is the first time I changed action on a bass guitar, so I might have done something wrong, but what? im thinking off bringing my bass to a tech and let it be set up perfectly, but that will cost me atleast 50 euro. On the other end if I change the string again and break I will have to keep buying new strings till I get it. So what to do? Just some info:

Action was really low
Strings were new, 2 weeks on there
Strings were "normal" gauge in standard tuning
String broke at the bridge

Sounds like a part of the saddle was sharp and cut into the string. Take a look at the bridge saddle and use a file to soften and sharp points on it. If that isn't the problem, that you'll have to wait for someone else I'm afraid

as you raise the string it puts more tension on it, like tuning up. that could have broken it
