You will have to play around but here is a quick basic guide. Easiest to start with an existing EQ, modify it, then save the changes under a new name. So go into Settings > EQ Settings > PMEQ and select the my EQ that you downloaded. It will look like this (with my EQ in this case named "3"): You then choose the Band that you want to change. Those are the round numbers. In this case we stick with Band 1. That is the full sub-bass boost. You then go to where it says "Type" and you can scroll to the right to find the "Gain" setting for the Band. After you scroll, you see this: As you can see, the Gain is 1.2 dB. Scroll up or down with your thumb to increase or decrease the Gain. Here we increase it to 1.6 dB: You can then switch to Band 2 and increase that a bit the same way. (I suggest increasing from 0.8 to 1.0 dB.) When you have made all your desired changes, touch the upper left arrow to exit. My thumb is beside that arrow here: Then Choose to "Save As". It will prompt you for a new name. Then you will have my original EQ plus your new EQ: You can change Type, Frequency, Gain and Q for each of the 5 bands this way. It is just a matter of scrolling around.
