Basically, the eyes broke because they got dirty and I played the whole day without cleaning them which I now regret
Well to change the eyes you must take out to screws for grip frame take out the old eyes then put new ones in, but I'll try and get someone to do it for me.
If your in no rush I'll try to do it.
Maybe within a week or two.
by the way: leaning the eyes is really easy I just ignored the situation, Ill tell you everything about maintenance later if you wish.
