Yeah, I have, and it is marginally improved, but still quite present.
Just to add some more info to describe the sound:
It's coming from the low-end of the guitar i.e. the bottom 2-3 strings, but it manifests itself as a nasty high end fizz/unnatural distortion. Is this some sort of aliasing??
I can certainly dial some of it out if I but a low cut on the front, and then put Bias and Bias X up full, but it is still there.
