Semi-Sweet Distortion 3 - EQ mod ?

[nkt$275]

I am interested in modifying the
Semi-Sweet Distortion 3 pedal to have less highs more low mids and lows. Can somebody tell me how I should go about doing this ?
Yeah, yeah I know - “Dude go play your G2.”
Because of the way the circuit is designed -
I figured I would learn something.
