Would I have to change the nut at all it I wanted to chage the strings on my 5 string from BEAD to EADGC? Would they rattle around in the slightly large spaces or will it be allright as it is?
I don't think you HAVE to. I'm not sure if it would effect the tuning or anything but I don;t see anything wrong with the idea.
excellent, 2nd opinion anyone?
I think you should change it. Even a small difference in size will make it rattle, and that's not a sound you want to hear. Always use the right part for the job.
You will not have to change it. I never did and nothing negative has ever happened. There will be no difference.
Only change it if you encounter problems. You probably won't need to.
Brilliant, now where the hell do I get a C string from?
A six string set usually.
