Alex,
I’m sorry we didn’t see this post until now. I guess it got caught in the spam filter. Sorry about that.
It’s odd that it was working for at least a little while and then it stopped working suddenly…at least i’m assuming it suddenly stopped working. Does the bypass LED turn on and off as expected? I’m assuming that you can hear the relay click when the bypass button is pressed?
Thank you for the photos. At first glance, the only thing that comes to my attention are that the leads on the “standing up” resistors are exceptionally long. You want to keep those as short as possible so they don’t short out against each other. Check to make sure none of them are touching.
Test the relay circuit by working through step 5-C of the troubleshooting guide.
When the bypass LED is on (and the guitar and amp are plugged into the pedal), turn the volume knob all the way up…can you hear any hiss being modulated by the tremolo circuit or is it completely quite?
Let me know what you find.
