Question for EMG preamp users... treble control.

So the EMG pre's treble controls have two switches for adjusting how the treble behaves. Which setting do you think would allow for the most treble cut? Which would allow for the most boost? I emailed EMG, but it's a Sunday and I'm impatient. Thanks for any input.

 

Thanks for the diagram. I do have the hard copy of this, but I'm not the smartest or most scientific guy. I think if I understand these EQ curves, the 1 OFF 2 ON position would yield the most audible difference in treble cut and boost? Specifically, looking to cut as much as possible.

 

Thank you very much for the speedy reply.
