for the quad opamps, i went with tlc274cn

out of all the quads i had, these seemed to quack and sound the best.
intersil ca3080e's a must
there's new video uploading as i type this. it sounds pretty good. i haven't quite got it dialed in right yet but its pretty close. it even quacks without the fuzz in front of it.
so for mods, i went with a 500k trimmer for r5, which sets the gain of the first stage. turn til it sounds unity for output.
for r19, i went 10k trimmer pot. can dial it in, again, to where it sounds good.
added a reverse biased 1n914 between d16 ground and ground, with the cathode of the 914 to ground. this raised the voltage supply just enough to make the circuit come alive.
c2 is a snubber cap for the fuzz. it sounds like ass with it in there. don't even install it. if you must, go as small as possible.
for d1 and d2, the clipping stage of the fuzz circuit, i went 914 and bat 41 on one side, and 914 and 1n60 on the other. sans c2, it gets a fairly useable and more robust overdrivey fuzz that way.
d3 thru 8 should all be germanium. it just simply quacks better.
i tried every dual opamp i had. to my ear, as predictable, the lowly 1458n sounded best. something about the way that chip sounds, dirty or clean, works for me. very smooth and not harsh.
i didn't implement the jack for an exp pedal, as i doubt i'd ever use it.
still think it needs just a touch more quack.

as ya can see, it had quite a bit of rework, so it looks kinda nasty. just flux and glass dust from taking out the 914's lol... did it from the top of the board. didn't wanna have to disassemble the dang thing.
i got 1:07 am here, est and it says the vid is 77% done being processed, so i imagine any time after about the next half hour it should be visible.
