I'm trying to rebuild the fuzz section of this amp. It is normal for this circuit to reverse the phase?

Based on this schematic, you can see that clean section is reversed compared to both original signal and clipped one

I used the original acoustic 360 schematic to build my version not the moosapotamus version. I also used a classic tl072 buffer in and buffer out with blend pot like darkglass b3k design to control the clean and clipped signal.

I solved the problem changing the blend control design. I used a differential amp as blend using inverting section for fuzz and non inverting section for the clean signal.

Somebody knows which HFE is used for the 2n1306 in the original amp? I'd like to replicate that sound.
