Nonetheless, we decided to add a few further enhancements to its already powerful design: selectable black/brown EQ mode allows the user to tap into the two EQ circuits that were peculiar of the console's different versions (with the low shelf knob color showing which one is selected).
This means that the dramatic frequency shifts and boost/cut ranges are available at the flick of a switch for instantaneous tone shaping possibilities, where the black mode has more inherent gain and sharper Qs, giving a more pronounced “EQ” effect.
