I believe I’ve read something on this forum (or maybe elsewhere?) about changing a resistor or a capacitor (?) on the 4PM filter board to increase the ‘ballsiness’ of its resonance at lower frequencies. Unfortunately I failed to retrieve that information.
Remove the 220nF cap near the LM13700, and bridge the pads.
anyone have an audio example comparing the before and after?

Could I leave the cap and bridge the pads through wires and an on/off switch so I could switch between ‘normal’ and ‘beefed-up’ response?
