Clipping Adjustment

I built the Windmill overdrive (Catalinbread WIIO) and I'd like to adjust the clipping... it clips a bit too hard for my taste. Which resistors should I adjust to make the clipping a bit softer?

Any help would be appreciated. Thanks!
 
I'm not seeing any clipping on this one. it looks like cascaded mosfet stages similar to the zvex box of rock.
 
@skrattadu Insert a pot between the Windmill's C17 470n & R18 200k resister.
Aion's Apollo circuits use that feedback-path potentiometer/resistor combo, B250k and 47k respectively. So check out those build docs to see how it changes gain, EQ and compression.



If that's not enough, then maybe try adjusting the amount of gain in each stage, ie each transistor:
Q1's R2 & R3
Q2's R7 & R8
Q3's R13 & R14

Monkeying with the gain of the transistors is going to have a knock-on effect, though, and may screw up the overall voicing of the circuit.
