Exactly what I am trying to do - if I could start out with a level playing field (excuse the pun) then it will be far easier for me to then start changing settigns for musicality. I am having a bad time of setting up at the moment using the empeg equaliser because although the equaliser is set up to be flat, I don't know what this translates into after it's been fed through the loudspeakers and amp. If I could look at what the empeg samples and then sets up as "flat after speaker output", then I would be able to say "too much treble" and wind it down. But I need to see what the spectrum looks like first, which says sampling. Since I haven't got access to a B & K audio spectrum analyser, then the empeg itself is the next best thing.
