So I see that it says "DOD - Sandy, UT" at the bottom... Interesting!!

Corporate secrets are out? Fucking WikiLeaks!!

And I still haven't gotten my complimentary Buzz/Meat Box clones for "leaking" that shit. ;_;

I should have a celebration in my honor, dammit!

Wow. Right on.
Well, I'm going to have to get past the first few pages of my old Radio Shack Electronics book before I'll be able to figure that schematic out!

Cool stuff.

Cool! Any chance you can tell/post a picture of what you did with the octaver too? Sounds very neat!

yes, i know.. i forgot to take a pic of the bends before i handed the pedal back to Herr Doktor... i'll see if i can get a pic of it....... it was also super simple. just made a short circuit and added a 1?F capacitor. voila. 8)

cool! I was kind of looking for some bitcrushing stuff and this could potentially save me some cash!

hey does anyone feel like making some 808 modules? Here you go then!

eric went through the trouble of sourcing currently available parts

look at that sexy schematic

lots of people have tried to sell PCB's or kits and so far no one has actually made a complete 808 PCB with no mistakes on it. if you get a working PCB out of it, you have 100 people ready and waiting to get one. hexinverter was selling some yummy PCB's but only one sound per PCB and having them in stock is hit or miss.

What I learned from circuit bending a Corned Beef reverb:

The "wall of delay" bend shares its point of origin with two other marked points, but I can't remember exactly if the second red-highlighted point is correct (that said, there are several points on the circuit that activate this bend, so it should be really easy to find going from the POO).

Frying the circuit basically just makes it so it won't delay anymore... I don't remember the second point to produce the synthy distortion effect marked in pink, but the one highlighted point is somewhere to start from at least.

The lines are drawn to show easier-to-solder points that branch off from the PT2399S chip.

PS: Apologies if anything isn't exactly accurate. Some of the bends are documented from short term memory.

This is a single supply VCA based off of the MFOS Noise Toaster VCA which is basically just a 2n5457 transistor, I added the opamps so you can bias the CV input and gain it up to 10x. It is pretty simple, but let me know if you see a mistake in it so I can fix it.

Do you have any audio samples of this thing? Looks short and sweet.
