I think you meant to say they are out of phase? In phase is not a problem.
If so it's very unlikely to be a QA issue and more likely a design flaw. Does the phase flip back again in hot fusion mode by any chance?
Add it to the list of things to fix for MkII, Two Notes!
yes sorry, I meant out of phase
nope, changing hot/cold fusion doesn't change anything... switching-on either one or both channels will put the two outputs out of phase
oh...another thing that happened - when first testing it, when switching form cold to hot fusion the pedal just went silent. Back to cold - it did what it should - than switching back again to 'hot' nothig... the hot/cold button was like a mute 'button'.
After switching the pedal off (plugging the powersupply out) and back again solved this one...and has never happened since...
... this makes me wonder - what is really analog/digital in this pedal...
