Another solid PCB from PPCB that has quite a few excellent reports out there, so I won't bore you with what this thing is.

It's a fairly simple build. Built everything by the silkscreen. Ran 510K in series with a 2.2M resistor to get very close to the 2.7M ones. Really, the hardest part was to find a good distance from the LEDs to the LDRs. At first, I had them right up against, but it became extra distorted so where I have them now is kind of the sweet spot.
There does seem to be some kind of gating effect going on that I've heard from back ICs so I may go back and swap to see if it fixes it. Other than that, I think it's working as intended. Unity gain is well under 12 o'clock but that really doesn't bother me. If I build another one, I may change the volume pot to an A50k.

It's not for everyone. It's like an orgy between a uni-vibe, a phaser, and a tremolo. It sounds really cool with some dirt. It's a bit noisy with fuzz but that can also be its charm. I'm having a lot of fun with it figuring how to get some good recordings with it.

Also, to be clear, this is, in no way, GB Packers colors.
