The EQ curve i use is a personal one - however, i used the published FM curves as a start point. when the senitivity to a freq band goes up in the curve, i reduced that freq in the global and vica versa. this is of course broad brush - but I fine tuned by ear. The settings were pretty close except the 1Kh band. That "should" (according to the curves) be the constant - ie thats the only freq whos apparent response doesnt change with volume, however i found I needed to boost it by a db or so to keep the punch at low level.
James is right about the gain as well. My patches have two gain levels (using the X and Y amps) and i find I use the low gain for live and the higher gain for home use.
ill PM you my global EQ offsets for home use once my AFX has finished updating the FW. they may not be right for your relative levels or your cab - but should be a decent starting place.
