I recently succeeded in building both a Feedback Loop and a Green Russian Muff Clone, so I thought I had the flow going. Turns out I was wrong.
My the last project, this: http://www.musikding.de/product_info.php/info/p1831_The-Tremolo---optical-Tremolo-kit.html
, didn't turn out as well.
I have soldered every component into its right place (I've double checked and then checked again), as well re-wired it twice. I've even tested every cable and soldering joints with a multimeter, but still... No dice. I'm not able to read the electronics schematics (http://diy.musikding.de/images/stories/tremolo/tremoloschalt.pdf
), maybe I'm missing something there.
I've followed the bill of material and placed everything in it's right place (http://diy.musikding.de/images/stories/tremolo/tremolobomen.pdf
When i connect it, I can run a bypassed signal through it (hurray) but as soon as I flip the 3PDT, there's no sound at all. And no light. But when I disconnected the LED I found that it was broken, still, that doesn't have anything to do with it not applying the effect to my signal, right?
I'm about to go to the rehersal space tomorrow to troubleshoot further, but if there's ANY advice on how to proceed, PLEASE give it to me. I would appreciate it immensely.
