1. In the Components section, click on the Tools tab and drag the Crossover Mix module between the Input and Output components.
2. Click on the Amps tab in the component section, and drag over the Amp that will process the low end (Gratifier is a good choice). Drop it between the Crossover Mix Low and High modules.
3. Set the Crossover Mix Crossfade control to 100:0 (all lows) and crossover Frequency to taste (try 600–800Hz). Now tweak the Gratifier controls for the desired low band sound; the preset “Punchy Clean – Bass” is a good point of departure, maybe with a bit more Bass and a little less Treble and Presence.
4. Click on the Amps tab in the component section, and drag the Amp you’ll use for the high band Amp between the crossover High and Crossover Mix modules. Lead800 (Distorted 800 preset, with Boost enabled) works for me.
5. Set the Crossover Mix Crossfade control to 0:100 (all highs) and tweak the Lead 800 amp for the desired high band sound.
6. It’s time for the finishing touches. Adjust the Crossover Mix’s crossfade slider for the desired balance of the high and low sounds; also experiment with the Frequency parameter, and you might want to spread the two bands a bit in the stereo field using the Pan controls. Rock on!
-Patching the Tube Compressor between the Crossover High module and the high band amp can give a smoother, more sustained high end.
-Enabling High Resolution mode (in the Control Center section) doubles the hit on your CPU, but also doubles the sound quality — highly recommended.
