Gravitation Reverb Distorting

Carefully dbl-check all component values. Without any photos to go by, I also suggest a solder reflow to ensure all is good in that department.
I checked the components and they are correct. I couldn't reflow al the parts because of their placement. The noise still exists. Could it be the op amps or belton brick?

It's possible that it's the opamps. Can't read all the part numbering on them. Can you say exactly what all the part ID says? Please include the batch code on them too. If they came from Tayda, they could be from a bad batch that are known for distortion artifacts on the decay of a note. Here's a short list of known bad TL071CP date codes from Tayda . . .

I did order them from Tayda.
TL072CP
21MDBWO (The Last O could be a Q)

I'll start by replacing them in that case and get back
