I'm not too concerned about conflicts with Q settings and whatnot. Like probably 90% of empeg owners out there, my EQ is set
completely flat, because fussing with those detailed controls is impossible when driving. Yes, I know I can park and play with it,
but I don't. And probably neither do 90% of the owners.

That's why I suggested to use bands 9/10 and completely overload any existing settings on these bands. With a low Q factor, it shouldn't be necessary to use more than one band to effect a bass or treble slider. People who still wanted to set up eqs would still have the other bands to play with.

Anyway, I'm only suggesting solutions for fun - I also have Bass/Treble control on a separate HU..
