Build Your Own Clone Message Board

Hello! I just finished my echo royal and am not getting any guitar signal out of either the dry out or mix out. When I turn repeats up the pedal self-oscillates though, so wet signal does get generated. The LEDs work as expected! Bypass works! It's just that I'm not getting guitar signal.
Any help is greatly appreciated! Thank you!!

Hi - welcome to the forum!

Well, this is a really difficult build and that's great that your pedal is mostly working. That cuts out a lot of troubleshooting. For now, all we want to do is to focus on getting signal in the dry output. That is the shortest signal path to troubleshoot.

The dry output signal path consists of the following components: C1, R1, Q1, Q2, R5, and C3. Inspect each of these components for value and orientation very carefully.

Follow the instructions in the following post and reflow the components listed above. I actually don't recommend reflowing the entire board at this time as you are getting wet signal out already: http://byocelectronics.com/board/viewtopic.php?f=9&t=52188

By far, the easiest way to troubleshoot this is to use a BYOC SIGNAL TESTER or an AUDIO PROBE. Do you have either of these tools?

One suggestion that I would make from a quick look at the solder side of your PCB is to trim down the component lead ends to the tops of their respective solder joints. These can be possible sources of power or signal shorts, particularly those close to a grounded metal surface. For that same reason, it's a good idea to insulate the backs of your pots with electrical tape or other non-conductive material.

Oh sweet! I just made a makeshift audio probe and found the bad solder joint on one of the resistors! It totally works now. Thanks so much for the help!!
And I'll be trimming down the component leads as soon as I get the snipper tool that I ordered in the mail, thanks for the suggestion!

Nice work! Glad you got the pedal working. It's a doozie!
