Yes! This setup is great if you are using stereo FX, or multiple amps (with different panning settings) in your rig on the HeadRush Pedalboard. 


For a stereo setup, connect the left and right main outputs on the HeadRush board (or other multi-fx/amp modeler) to two separate FRFR cabinets; one speaker connected to the left output, one speaker connected to the right output.
