  4. Sorry I have one question: LED+ means that a wire has to go to the positive of the LED only? or do I have to connect that positive also to the DCjack? thanks :)

  5. Hi, I just want to pint out that the lower op-amp was indeed a TL072 instead of an 4558. Did anyone already verify the schematic/layout? Tracing the pedal was a bit hard due to the black solder mask...

  6. Verified! Tried 4558 in both positions and TL072 in bottom position. With both 4558s you get a faint hiss in the background but not with the TL072. Thanks Alex.
