Awful Waffle no sound

[Texasbluezman]

So, I'm assembling my 3rd Crowther Hotcake/ Awful Waffle pedal from PedalPCB. The first two worked flawlessly at first attempt. I sold those two. Then I got a request for another one. But this one's not acting right! Lol.

I first assembled it with the foot switch on the right with the foot switch PCB in pic 1. I had clean sound with the effect off and I had a good overdrive sound with the effect on. It sounded just like the other two. But I had no LED when turning on the pedal.

After looking at the wiring diagram I noticed it didn't have the foot switch PCB. So I installed another foot switch, wired it up the way it is in the wiring diagram. Now I have no sound at all, but the LED light comes on when turning on the effect.

I included several pics to see if you guys could see anything wrong.

Now I did use an audio probe. I was getting sound at the input, in to C1, through R1, to pin 3 of the op amp, but no sound out of pin 6. I have four different op amps here and have tried every one of them with the same outcome. They are not all from the same company, so it's not like I got a bad batch of lm741's. But no matter what, I can't get sound past number six pin of the OP amp. These pics do not have the LED installed.

This one's got me stumped. Also, I'm not a total noob, I have about 20 pedals under my belt and have been doing this for about a year now. Help! Thanks in advance!

In the third picture, it looks like the jack on the right is wired backwards. Is it?

Don't think so. Here's another pic.

Wiring looks good. Must have been the angle.

All your values and orientation that I can see look correct

If it worked prior to changing the switch I'd perhaps first check / reflow the connections you changed

I got sound when I had the breakout board installed. But why wouldn't the LED work with it? Can the breakout board be used with this pedal? The foot switch is wired differently than other pedals. I'm going to change out the foot switch and put the one with a breakout board back in it and see what happens. I've done more than reflowed, I've changed out the foot switch twice and the LED once.

I just received a new board and will be populating it in the next couple of days. I won't be going anywhere, got tropical storm Nicholas heading my way.

The gulf has seen a lot of activity this season. Stay safe.

Thanks fig! I just wish this pedal would work. Hopefully it will with this newly populated board.

I still don't know why it wouldn't work. I got another board and assembled it and it worked perfectly the first time. I'm gonna hang onto the board. Maybe as I get more knowledgeable, I'll get it figured out one day.
