Parasit Baxandall tonestack debugging (SOLVED)

I think the Tech21 bass amp pedals have some good ideas to pick at.
The input amp is properly protected and gives some initial gain. The input impedance is high for guitar/bass use.
The output has a protected opamp buffer/line driver.
The low and high bax filters before the output buffer are preceded by a mid control.
The volume control is before the EQ so can also be used to keep any EQ in boost from clipping.

Why is having the mid control before bass+treble a good idea? I noticed Gallien-Krueger preamps are like this. I remember reading somewhere Bob Gallien did it like this for noise reduction, but no further explanation was given.

If the mid section provides an overall gain, it can present a larger signal to the Bass/treble part and that would improve s/n
