I've replaced mine before and it sounds fine but when I tried to replace my friends on his guitar it started buzzing more when plugged into an amp. We changed it out cause the piece was rusted and kept falling into the guitar. How do I fix this? Also I'll note I tried to remember which wire went with which post while soldering but it's very possible I got them mixed up.
Did you replace the actual jack or just rewire/re-solder the old one?

I suck at soldering though for some reason. Whenever I try to desolder it doesn't melt that well. I thought maybe it was my iron but I bought a new one and it doesn't work that well either. I think it's me.

Thanks for the advice though. =)
yeah, your soldering doesn't have to look "perfect", but it must make good contact.
