Vibrobot distortion

Calling @DGWVI and @Mentaltossflycoon and anyone else who might have thoughts. Mkay, not the reason I thought I was going to open this thread, but while my vibrobot is trem-ing, it has some distortion/fuzziness on the signal. After chasing rabbits before lifting pin 6 I am 99% sure of parts values. During the no trem witch hunt I also have reflowed joints, cleaned the board, the voltages look good, the ICs aside from the 8038, that I got from Robert, came from Mouser, I have messed with the trimpot, but can’t get the signal clean. Obligatory board pics in case I missed something and also a vid for listening purposes. My initial suspicion would have been the TLC2262 except with the depth all the way down the clean is clean. I guess that leaves the 741, 8038, or the 2N7000, but are those actually seeing/producing an audio signal? The vid was made using my p-90 loaded Reverend in the bridge position, but I also tried with my tele and although there is less, the distortion is still present.
