I need the collective brain power of this fine forum please to help me solve this... I have two PedalPCB pedals - a Kliche Mini (Klon), and a Cetus (Victory Kraken). I'd like to think I build quality pedals, with clean soldering, and clean, minimal wiring. Both pedals use a charge pump to bump up the voltage to 18V. I'm using high quality charge pumps, and a high quality isolated 1-Spot TruTone isolated power supply. My problem is this...
If the Kliche is placed before the Cetus, the Cetus emits a high-pitched whine when on. This is regardless if the Kliche is on or off (probably because it's "always" on as a buffered bypass pedal). Switch the order of the pedals, and no whine from the Cetus. I've switched out the charge pumps (other 1044CPA's). Also, same problem if using 9V batteries, and not the 1-Spot power supply. Removed all other pedals for this test video:
And the gut shots:
Open to any and all suggestions! Thanks.
