I tried that with a Boss 7 band EQ.. just raising the volume fader, didn't work so well, made the whole sound alot fatter with just a small notch of the fader, alot of tone coloring for a very little volume boost.
i'm currently using my Monte Allums od-308 as a boost, volume at max, tone at max, and just a bit of od to crank the volume. it sounds allright, but could be a bit brighter. the tone definitely contrasts with the rythm tone however.
