BOO-Q eq refinements if needed please?

[screamersusa]

Still messing with mark2 crap. 
I noticed the MK2 pre-eq adds an interesting and important aspect to the tone so
I built one full one. Then I tried to whip up a Big Muff type control to get the same curve
that is the average setting many people use. Bass 3 mids 5, treble 7.
I wound up with something interesting.

In the TSC fender setup, plug in the boogyman numbers:
c1-250p   c2-100n  c3-47n   r1-100k r2/r3 250k logA,  r4-10k.
set it for the boogie average setting , bass 35%  mids 50-60% treble 75%
take a snapshot.

set up the big muff as follows:
c1-2.2n  c2-22nf  r1-36k  r2-200k r3-150k lin. (you either preset the resistors or add a 50k pot and 100k instead)
set the big muff to 75% and bang you have a similar eq curve with 8-10db less loss. 
I wound up using a 50k pot from c1/r2 to a 100k into c2 to have a little variance.
I went with a 50k pot instead of r6 yielding a bit of control over the mid cut and winding up
with a slight high mid boost with the pot all the way off.

I'll drop a mini booster before it to make it close to unity.
Sounds pretty nice before gain stages without as much loss as the standard boogie eq.
I wonder if someone could scale the boogie eq for less loss like the russian guys do
with bigger caps?
cheers
