I don't know what to call the things you adjust to tune ur strings. I think you know what I mean. It is really hard for me to get the strings 100% in tune. As I move just über little, like 0.5 mm, the tune travels far away. What can I do to make my "tunerscrews" not so sensitive? Do I have to many wraps of the string around it? Too old strings? I want the sensitivity to be cut with half effect. Sorry for my strange english - I come from sweden.
