It does act a lot like the Hyperion 2 ground lift oscillation.
Are you having issues with your 2 Builds ????
Newest one
Have you tried lifting one of the grounds from the Input/ Output jack ????Any suggestions how to fix this? Should I run some grounds to the enclosure like in and amp? Or connect the in and out grounds together? Maybe run hounds from the power jack to the In/out grounds?
I think we need to audio probe and see where the oscillation starts. But seriously, I'm not probing this guy.Any suggestions how to fix this?

I have. No dice.Have you tried lifting one of the grounds from the Input/ output jack ????
I have. No dice.
It's not a high squeal. It's a tunable full frequency oscillation.Only quick fix I can think of is try some 220pF caps from grid to anode to kill that super high end.
Hook the pot up to a string on a slider, and enjoy your new ondes martenot?It's not a high squeal. It's a tunable full frequency oscillation.
Have you tried a Buffered pedal in front of it????It's not a high squeal. It's a tunable full frequency oscillation.
Holy that solved it!Have you tried a Buffered pedal in front of it????
That doesn't do anything for me. Its self oscillating.Have you tried a Buffered pedal in front of it????
Check your Resistor values to & make sure you you got the 4th Multiplier Band right ??????That doesn't do anything for me. Its self oscillating.
If the traces are too close why does the buffer correct it on my build? Just lowering the impedance is the trick?I never have oscillation issues as I always have buffered pedals amongst my true bypass pedals!
It will be a Trace within the PCB sitting too close to another Trace!
This is High Gain so it is more prone to squeal in a confined space!!!
Yes, well beyond the basic troubleshooting, up to high voltage probing.Check your Resistor values to & make sure you you got the 4th Multiplier Band right ??????
If this is the solution, then the pedal was designed to never be used alone without a buffered pedal before it?! That isn't logical. Or it would have the onboard circuitry to function on it's own.I put the Black Eye “AFTER” my General Tso as it has a BP, and Whala! No squeal full blast vol or gain. Sweet. Now I need to built a tiny Bp to stick in front of this beast because I don’t want it after my General Tso. Thank you @music6000
