Heads up Moonn is a one-person shop and can be slow to ship, sometimes by weeks. Orders do arrive; allow for the wait.

From the vendor

This is super fucking straight foreward You can use this PCB to build a clone of the Ehx Big muff. But the one that uses opamps and has a tone bypass switch You can use it to play some Smashing Pumpkins riffs and ignore that Billy Corgan is a transphobic pile of garbage! Or everybody can stop only referring to that idiot when talking about this fine pedal Everything is fine... We just don't hold people accountable for their bullshit if we still like the art they are producing but everything is fine...
