I've got one in the mail, shouldn't be too long till she's traced.

easy , a big muff with a phaser filter with no LFO (a pot connected between V+ and ground) . But no need to see the guts to know that the video clips are enough.

Hope that you'll do it soon! I can't wait to build this pedal!

I even say that's a Ross phaser (3n3 caps ) . And I though Malekko was original in designs

Little late but finally finished tracing. Is indeed a tweaked muff into a ross phaser with a pot to the reference voltage instead of an LFO. Super cool pedal, only thing is it's non-true bypass stock and sucks tone worse than an old crybaby wah. Piece of cake fix though, there's 3pdt switches in there standard and one pole isn't used so here's a pic of how to fix it too.

muff section:

Phaser section (all the 1.8k resistors are 1k, sorry):

Mixer circuit:

Super messy trace pic:

True bypass fix:
