Resoldering the pins was my initial plan but I figured it would be better to get new terminals and recrimp them as it would be more reliable as the terminals are really delicate and and change to the shape could make the connection fail.
I spent some time on the molex and a few other sites trying the find the right connector but couldn't locate a match so I thought best to try line6 directly first, either if they could replace the part, send me some terminals or tell me which ones are used It would be better,
In the worst case if I'm on my own I'll just solder it and use your tips to prevent the solder flowing in the wrong parts.
