Hi. Just bought a jtv-69 (korea made) today. But... a big problem... when I am playing a bit hard on the notes mention above i really get a terrably sound. Its like its distorted. (neck picup) This is not happening to the magnetic picups and not to all other models either. And even on the same model (spank) its gone when I am using bridge and mid positions... I also notice like a flanging sound on several of the models... I did reinstall the software 1.90 but it did not help :-( so I think I will return it someday soon...

Any ideas?
