Question...

At what volume do you normally listen to the player at? For instance, if you really crank it and you're rocking out and the speakers are at about the maximum they can handle, what does the volume readout say on the empeg screen?

If, in that situation, it's low, for example it's lower than -10, then your problem is simply that you've got your amplifiers turned up too high. Turn the amps down to the proper levels and you most likely won't hear any sort of electronic interference, tuner or otherwise.
