Guitar Sounding Weird

My beloved wife is starting to sound weird especially for the last 3 strings which is 3G, 2B and 1E. Actually last time I did modify the saddle and I don't think the modification was done nicely. The last 3 strings have a weird sound when I hit it. Darn need to get back my old saddle and try to fit it in or I will need to modify the current saddle. But the thing is, I am freaking lazy to unstring the guitar and fix the saddle. It is so much hassle. Maybe I should just leave it.
