One big advantage over the original Pultec design is that the LC EQP affords the option to set the boost and cut sections to different frequencies, giving far greater flexibility and the ability to tune the dip more effectively. The outcome is low-end weight with mid-range clarity, which is usually exactly what is required, and not something that can be achieved with a simple LF shelf equaliser alone.

So if you want to boost the LF, the cut control (set to the same frequency) introduces a dip at the start of the shelf which helps to minimise the mid-range muddiness that might otherwise result. Although the ability to combine both LF cut and boost simultaneously might sound odd, it actually works remarkably well, just as it does in the Pultec, because the shapes of the curves are different and the way they interact produces a complementary EQ 'change of direction'.
