The ESP Guitar Company

hi, I own this guitar since a week and wanted to do some slight modding. I just dont want to do any drilling and making new holes but use the existing ones.

-Is there a certain string roller people can recommend?

- is there a locked tuner people can recommend that fits the existing holes?

-adding a pickguard is not possible I guess?

-my switch has some problems, I noticed the ground cable was not connected so I resoldered it, but the switch cracks and in the middle position the neck humbucker is not playing.

there are three cables connected to the PU Switch, but they are very short, I don't think I can pull enough out so I can solder an new switch easily. I pulled a bit harder but it's just enough that I can get the switch outside the hole.

any tips?

I know the guitar is new I could have just sent it back, but I am sentimental, I kind of like her.
