6-Band EQ Squealing


New member
I finished a build for the pot version of the 6-band EQ circuit. It has a major squealing issue when any of the pots are past mid-way. If I turn down all the pots I can turn an individual pot higher than mid-way without the same amount of squealing although all the way up it'll squeal.

Any thoughts? I've done all the normal checks for soldering and loose connections. This isn't my first pedal by a long shot.
Reviving this for a moment: After reading some other threads about long leads to pots I'm going to try and shorten them. This PCB is a wacky experiment where I am cramming 3 pedals into one enclosure and I have like 3" wires per pot.
