EQ2 is still very new, and the PEQ was around for 10 years before we replaced it. The current EQ has expression via the control input with our expression pedal, or using a Y cable to flip the top and ring connections with a third party pedal. Also there’s a dedicated thread to the eq2.cannot find a proper topic for EQ2, so I'll leave a thought here. would be great if the next incarnation would have expression pedal input, so user could tweak left and right channel differently and gradually change left → right / right → left this way. should be a nice 3d thing, I imagine. or a normal sweeping between presets. another thing is to make a sophisticated filter with it lo/high-pass style. like you choose the start/end band and then you shift with an expression pedal the whole segment left and right.
