.. And how to use them.

Well, that my question, how to use them? :D

I recently bought an MXR Ten Band EQ pedal because I'm fed up with trying to get a decent tight distortion sound out of my amp (Orange Crush 35RT and I play Schecter Humbuckers). I don't like the dirty channel of the amp, so I'm using OCD & TS9 Pedal. So, with all honesty, I'm lost with all the numbers and frequencies and such.

Some guidance would be much appreciated. Thank you.
