You
really seem to
like random bold

.But...I jest.

You're being quite vague, but I'm not sure you realize that you're being so. What exactly do you want help with? Just saying you want help with "
eq configurations" is a really wide sweeping arc.
What
exactly is it that you want to achieve?
In case you're not aware, the Rockbox EQ is a full parametric equalizer, and is very, very powerful. Basically, if you are not aware of what a parametric equalizer is, and/or need to ask, you probably shouldn't touch it at all.
It gives you the opportunity to do some extremely stupid things, without the foresight of knowledge, and it is sorely tempting to utilize all 8 bands of the EQ and the high and low shelf filters, but you should absolutely not do this.
Not only is it terribly inefficient to do so, there's absolutely no reason to. Most leveling (which is the only real reason you should be using this EQ) will only require 2 or 3 bands tops. The other bands exist primarily so that users can select from a specific frequency range easily.
Basically, if all you're wanting to do is color the sound to your liking, you should forget that the parametric EQ even exists, and just use the bass and treble settings.Not only is this easier for an end user to grasp the concept of, it is less hassle, and vastly more efficient (read as : 'uses a metric shit-tonne less processing power, and in turn, less battery').
