Hmmm, have you never been 100% with the tone of the Ray?
I have my EQ on the Ray flat, sometimes with a slight treb/bass boost, but they both punch like crazy. Seriously aggressive tone which is the main reason, (and the oval plate) why I wanted one about 12 years ago.
Is the ESP active? I'm guessing it's not.
Boil the ray strings in water/washing up liquid for 5 mins, rinse thoroughly, then see if that helps?
