One more.
In this pic the white is four quick points of PEQ including a shelf. I didn't save the details though. Still in the quick and dirty phase. The yellow is just a 4.5uF cap. This swallows 15dB of dynamic headroom from the midband and 18dB when the 3.0uF cap gets used.
Rob if there is anything more that you wonder about the 4338 let me know and I will dig up my later work.
