I have been having the plinks for about a year now. I have noticed it's not consistent and sometimes it's more pronounced. To diminish the hiss i get from my e string, I have been turning my tone knob down incrementally until the hiss is removed. Then i adjust the settings on my amp, usually removing most of the bass and turning the treble up all the way. I'm don't think this is pickup issue or a hardware issue but more of the way the modeling is registering high frequency from the e string. Hope this helps some of you, I'm sure it won't help everyone.
