A reply I got from Skreddy when asking about the pedal: "it's definitely just a "Big Muff" style fuzz, same idea as the Pig Mine (which it is replacing). But it has a clearer voice, better balance on the eq, and lower noise. I just quietly made the switch yesterday evening. I had been working on the P19 for months and finally decided I was done yesterday after revisiting it to confirm that it does indeed sound good with fresh ears and does not need any improvement. It has the ability to get lower gain sounds than the Pig Mine, which was always high gain even with the sustain knob set way low."
Lol, I sold my PM a few months ago, now I wish I had it so it could follow the same path as the PF and Mayo - get my $400!
I had also briefly talked to Marc about the need for a mid-hump on his pedals in a Fender amp - that I was thinking of rehousing a LM with a TS9 Silver to run in parallel. He said it was an interesting idea and never thought of it cuz his Hiwatt has plenty of mids. If he makes an LM with this feature, and I have some money, I would be in for sure. I doubt he 'took my advice,' per-se, but I am glad to see this option and I hope it becomes a trend!
