Jill,
If it helps, I use the factory default on the Mic e.q. settings. To get this, go to the Mic Settings page. Be sure the top line is selected. Then simultaneously press the up and down buttons at the bottom of each row.
As far as effects, I use Hall 3, set at 25.
To set this, press the Direct Access button then the mic dsp button. That will take you to the effects screen. I believe it defaults to Hall 2 Rever. Use whichever you prefer. If you use the Mic Dsp, I would suggest Echo, at about 25. This way you will always have reverb and the Echo can be turned off and on at the Mic DSP button as you wish.
For the overall keyboard e.q., I set up a User settings. I boost the extreme low about 2, Cut 100 about 2, run the mids at zero and boost 8k about 3.
Just something to try. To access the keyboard e.q. page, press Direct Access, then Mixer. From there you can select Edit and experiment.
