Hello! First post here!
I recently purchased an ADHD off a builder on Reverb and while everything works correctly (though it sounds nothing like an OCD v2) when the buffer switch is set down (can't tell if engaged or disengaged) the pedal generates a super loud feedback loop, with a tone sitting nicely about 200hz. The pedal only produces this sound when *not* engaged. It also changes pitch when plugging in/unplugging cables. When the buffer switch is set to the up position OR the pedal is turned on, the noise/feedback stops. Power cycling the pedal does nothing and no input is needed to generate the loop noise, only a second or two of time for it to ramp up. Buffer switch is the 6 posts soldered on the top left in all pics.
I took a peek and didn't notice anything particularly wrong or obviously loose. Pics included.
