Mantle Fuzz output unity at full CW.

I built two of the Mantle Fuzz (Blue Box) pedals and both work great, sound identical. Although I don’t reach unity volume until the Output knob is turned fully CW. It’s not necessarily an issue as I am able to reach unity volume by maxing out the output knob, just curious if that’s a bug or how the pedal is supposed to work. In watching demos on YouTube of the MXR Blue Box it does seem that most have output maxed out (or nearly there) as well, so maybe it’s correct. Perhaps someone who’s built this can chime in?

Both pedals built side by side, all components tested prior to installation, solder joints are lovely and board thoroughly cleaned as usual.

Thank you kindly!

EDIT: Just watched a few more demos and one of the videos mentioned “The output knob is utterly useless and needs to be maxed in order to be at unity”. So that answers that. I’ll leave the post up in case any other have the same question.
