Ok, thanks so much for all the help. I ran jumpers across the jacks and now I do get sound. Progress! However, when the pedal is engaged I still seem to be getting the bypass sound. Turning the pots, flipping the switches seems to have no effect. I should also add that there's a slight hum. I'm off to work now, I'll try remeasuring the ICs later. Thanks again.

Well, battery might be an issue after all... I plugged the pedal into the power supply on my pedal board and IC readings look pretty different.

Thanks, I'll go over the pots again and see what I can do to improve things. Yeah, I'm using a battery - though it was unused until I plugged it in a day or so ago. (Multimeter says it's pumping out 9 volts FWIW.) It's been in my basement for a year or so, I wouldn't have thought it would lose a charge that quickly. I'll see if I can't plug it in and retry the multimeter. 

I got my diodes either from Mammoth or Tayda. And no, I did not test them. Yes, I will test and or socket them in the future.

Yes my soldering isn't great -- I'll work on it and look closer. But from my vantage point, I think it's solid enough I don't think contact with the pots is necessarily the problem? (Man I hope my judgment doesn't prove totally wrong on this.)

Anyway, I did measure the ICs with my multimeter. Please bear in mind I'm just learning how to use the thing, and for some of these the voltages were jumping around a bit. For the measurements I started with the corner (the square soldering pad and worked my way back, and for the second row I returned to the front and again worked my back again.) Many thanks for all the help.

Ok, I soldered the sleeve from the output to the sleeve from the input, which was already grounded. Now there's no hum, but still no sound. Would be grateful for more ideas about what might be wrong. Thanks!

Thanks much. I'll give that a try when I get home from work.

Forgive my noob-ishness, but what's the best way to ground them? What lug -- tip, ring, sleeve -- would I solder? And to where? Just to the enclosure? Or somewhere else?
And thanks!

Thanks in advance for for any help here. So I've messed around with some veroboard and PCB stuff before, but this Kingslayer is an order of magnitude beyond anything I've previously attempted. I've had this Kingslayer board sitting around for a couple of years (It's the 2012 ed.) and I given that I don't have the time for hobbies I wish I did, I've put it together slowly over the last year or so.

Anyway, I finished it, it lights up and the switch seems to work in that it turns on and off. But there's no sound -- I am getting a hum. Things I've done -- I double checked the wiring, cap and diode polarity, component values, inspected the board for soldering issues. (I recently won an Amazon echo in a raffle; and it has an app that lets you read resistor band colors out loud and it will tell you the value. How cool is that?) I slept on it, and checked it all again. I've swapped out the two ICs one at a time for different ones of the same value and tested it to no avail.

Some known issues with the build -- I put in the wrong component (IIRC, it was a resistor) and had a whale of a time getting the desoldering gun to work and really did number on one of the pads. I was worried that it wouldn't work, but once I got the right part in there the my multimeter, which FWIW I barely know how to use, confirmed it was working and registering the right value. In general, the board and especially the switch is kinda sloppy. I forgot to do all the flat components at one time, a mistake I don't plan on making again. And in terms of soldering, impatience and inexperience are a bad combo -- I'm working on it! -- but I think the soldering is adequate. I've never used these plastic stereo jacks before -- possible grounding wiring issue there? And I have only tested it on battery power, haven't plugged it in yet.

Anyway, here are some pics and a copy of the old build doc. Since I'm self-taught from the internet and have no technical background, I'm hoping that there's something really boneheaded I'm just not seeing. Yes, I know, rock it before you box it, but I just put the switch and jacks in to make it easier to put cables in and out to test it. And yes, my experience with this Kingslayer means that building a testing rig just rocketed to the top of what-to-build-next.

Again, thanks for any help. I aspire to be the guy here providing advice rather than begging for it.
