    Here’s your problem, you have two wires reversed on the PCB. Follow the diagram and your pedal should work.

    Hello Ned, I finally managed to get a camera to get some decent pics, here are the links since they are BIG

    I also tested out some things:
    I soldered the ground cable. (nothing changed)
    I unsoldered (sp?) the pot and tested it with an oscilloscope and a signal generator…it works (I used another pot to see how it affected the signal, the one of the muff did the same thing)
    I tested connectivity on components and cables and it worked (the only thing I might doubt is working is the push button/switch thing, I’m not sure it’s connected correctly but I would say it is, no reason why it wouldnt be)
    Tested the transistors to see there had no connectivity between the legs (none), they are all working, even managed to read the 0.7V of saturation.

    And then… I stopped, I have no idea what might be wrong, I hope the pictures help :)

    I will test connectivity between the components on the first phase of the pot just to see if everything is ok, and I’ll look for a camera to get the pic (that would mean later tonight or tomorrow morning), thanks for your time! really!
    (I noticed you post on the HC as well, and that you DO love the Muff ;) that’s really cool)

    I tested the pot with a multimeter today,the resistance did vary, i also did a re-solder of the loose cable….and i get the same results :(

    EDIT:sorry i edited your post, I was meant to quote it.

    Did the resistance vary when you didn’t turn it? because if it jumps all over the place its definitely got a problem.

    Nope, it only varied when I turned it.

    that’s what I thought, do you know what kind of pot it uses?
