Natural harmonics

Hey guys. I have a question on the subject... Every time I change strings, my natural harmonics sound awesome... But after a gig or two, the sound gets worse, up to the point where sometimes I can"t even get them on 5th
fret. What is the problem here? The strings? But after only one night? :confused: I have medium jumbo frets, hss configuration. Usually I put Blue steel, Dean Markley I think it is. 0,9 gauge. Anyone has similar problems? Or can help me put here?

From what you say, it has to be the strings... I probably change mine on average after 2 or 3 gigs, though one of my mates changes after every gig.

I've never had the problem, but if it happens consistently after the strings have seen some action - that has to be the logical cause...

Try cleaning them with alcohol. Sometimes the goup deadens the string.
