Add Dirt
For dirt, firstly try adding in some of DCO2 alongside DCO1 and modulate the ‘tone mod’ using an LFO. Or use the resonance slider to add more drive and dirt; try both filter modes here for different effects – the 12dB has more grit in the top-end. Try using a single LFO sent to filter or pitch (or both) at a high speed and medium depth to add audio rate modulation (for adding growl/texture). Then try the Bass Boost which adds more girth, plus white noise for additional vibe. Finally, you have several dirt-inducing effects to employ singularly or simultaneously including the multiband distortion and rack amp.
