Casio SA-2 distortion bends?

[phantompowers]

I'm bending an SA-2 at the moment. I have found the drum triggers and the 5th switch but I can't find the distortion bend. Can anyone help me?
I have seen the X-fade Sa-2 on Youtube and he gets some awesome bass out of it. Does anyone know how to do that?

just search the forum; dj synchro explains it somewhere

Yeah, I've got it now, thanks.
