Skeptical buffer introduces noise when harmonics switch engaged

[MikeTinsley]

Just a quick one - my Skeptical Buffer sounds fantastic apart from introducing noticeable noise when the Harmonics switch is engaged - the Brights switch also introduces a very slight (almost inaudible) amount of noise when engaged. Has anyone encountered this before (and hopefully solved it!)? Any and all help gratefully received!

Thanks,

Mike

Hey mike,
Mine reacts kinda like a wrong biased fuzz when going through my dirty channel. does it feel like that to you too?

Hi Ian,

No - the musical sound is fine, but the Harmonics engaged adds a bit of crackle type noise - a bit like static even when no note is played

Any solutions to this one, I have the same occurrence going on. When the pedal is engaged with all switches off, its silent, if I add harmonics or bright switch there is white noise sound coming through (harmonics far worse than bright) and none with the low switch.
I cant seem to tune it out with a noise gate in the chain afterwards.
Interestingly some other pedals after in the chain can tune it out - I think my lowtide was one of them? Not sure if its a buffer issue there.

I've switched 1044 charge pumps out with the one in my Kliche, didnt seem to change anything. Tried it daisy chained and not daisy chained on my Iso-Brick (no change with either power)
I see another poster with a similar issue here too

Never got it figured out. I know in that previous post people suggested seapping out IC’s, but nothing changed for me.
