Anyone add the AMZ Presence control to the BSIAB II

[KrazyKarl]

Hey, I saw a thread about changing the BSIABII tonestack values to be the amz presence control 2 values here:

I was wondering though, has anyone actually tried putting it in series with the existing tonestack the way the presence control was meant to be?

I did it - sounded good, but I liked the GGG BSIAB II 'Contour' mod better; just involves changing one resistor and adding a pot.
FWIW, I ditched that and went back to the single tone control; I found myself messing with the tone/contour knobs too much.
