Hello people, this is my second build. No idea what's wrong with my Hydra Delay; The LED does NOT turn on (and no, it's not broken. I'm assuming the flat spot on my LED is the Cathode and should go in the hole labeled "K"). Then there is another problem; When I turn the on the effect, I can hear my clean guitar signal but when Mix is at 100% wet, I cannot hear anything. With my guitar volume maxed out I can get a barely noticeable audio signal. Using my headphone amp I was able to get something that's at least audible, though the signal sounds dry to me. I have used an audio probe to check pin 1 and pin 28 on my FV-1 (that I have soldered myself) and I do get a signal on both pins (though the signal coming out of pin 28 is moderately to significantly quieter, which is to be expected(?)). I have measured a couple of pins and the ones that I have measured are all "alive". I have also checked R17 and pin 7 on IC5. I get the clean unaltered (though quieter) signal on those as well. Any ideas? Pictures can be found here. The schematic can be found here.
