I've built from bodies I've gotten, never started from just a block of wood.

Yeah, same here. I think my most played guitar is a Telecaster I put together when I was 14 or 15 years old.

There's also area about guitar building here: http://www.madbeanpedals.com/forum/index.php?board=64.0

Hey!

So whats wrong with it? No signal at all?  Audioprobe is usually the easiest way to figure out where the signal is lost.

Also, post voltages from the IC.

Nope, just like the docs say: C5,  C6,  C7 and regulator are not needed.

If the original switch is SPDT then DPDT gets the job done. Use the extra row for the leds like this: http://i.stack.imgur.com/qkf9a.png

Adjust the resistors so that the leds are similar in brightness.

Post a schematic if you need more precise help.

Edit. Forget the latching switch on the picture.

Went through all the components again. All resistors, caps, pots, ICs, diodes and transistors are the correct ones. It's got to be a bad transistor or IC somewhere. Or broken trace or bad solder. Now I wish I had socketed transistors on this build. I think I should have spare one of every IC except MN3007..

Hey!

I changed both IC7 and IC8 and it made a change: now I get this weird distorted signal when attack is set between 8 and 10 o'clock. When attack is set above that no effected signal is getting through. I recorded short video to show how it sounds: https://youtu.be/d9TOt1thvUI (It sounds like its oscillating, but its not. First blend is at half, attack at minimum. Then I rise attack and only clean signal gets through. Then I max out blend and turn the attack down to get signal through).

All that noise and weird sound is introduced at IC11. Input of IC11 is fairly clean.

Soo.. Any ideas?

Hey, I'm sorry to see this so late, and I imagine you've already checked this. But anyway, in your picture of the solder side of the board, I see what may be a joint with too little solder on the top row of IC6. I haven't built a Rust Bucket myself; this is just what I think my eyes are seeing! 

Thanks, I just reflowed all the connections of IC6 (and lots more)!

No offense intended but there's a number of solder joints that look a bit cold. Especially on the pots. Also double check that the body of your resistors isn't too far in the hole and not making proper contact. A little flux and a little more heat should help a lot. 

No offense taken! I added more solder and reflowed bunch of joints.

Here's up to date pictures of the board (these are pretty large, so I don't want to attach them here):

Hey everyone!

I just wanted to let you know that I'm still fighting with this one. I replaced all the resistors with correct values (no more biggybagging, yay). Sadly that really didn't change anything.

I started messing with audioprobe while strumming guitar and turning all the knobs. I realized that Sense and Decay -pots don't do anything. There is no delay effect if I audiprobe from for example pin 2 of IC11. Could this be because of bad CD4013 or CD4066? I need to try find couple of more of those (usually buy extra ones, I just need to find where they are..).

Any other ideas are welcome also. I'll take new pictures as soon as I have time and its still bright outside..

Never did much for bass strings either.

I think it helps for a week or two, then they go back to dead. Totally not worth it.

Best advice I got when doing first SMD was to get really thin solder and a flux pen. Made it really easy!
