I just got my GK Neo 212-II in the mail, I hooked it up to my 1001-RBII and started experimenting with volume control and such. I've found that when the amp gets a pleasant overdrive from turning up the volume and boost (and turning down the woofer) the tweeter randomly farts out on some notes in a high-pitched buzzsaw kinda noise, mostly on the E string. This is all at bedroom volumes on bi-amp mode. Could there be problem with my tweeter or could I just be pushing it too hard? I'm also using kind of a lousy cable.
