    Hi guys,

    I bought diy fuzz pedal from ebay and it came without any scheme or anything at all.

    Can anybody help me what should i do ? I am a new at this.. I need to solder in, out, led, battery socket, 9 pin on off switch and adapter input.

    If you need any info that is not in photos just ask me and i will upload them asap.

    I would appreciate andy help :)

    Wow. We should be able to figure it out with enough pictures, but first things first - ask the seller for instructions!

    Well we should be able to map it out - can you post a similar close-up photo of the other side of the board? There's really not all that much to it.

    Most looks pretty obvious - the LEDs and thier polarity are clearly marked, as are in and out. Looks like power in is the two largish holes on the edge of the board, with the corner being negative, and the other positive. The actual switch on the board is only 6 pins, with three being an audio bypass or effect to the output, and the other three controlling the LED indicators. Not sure what they have a 3rd set of poles on the switch for, unless they are also switching power when it disengages, and omit the 'out' LED, since there will be nothing to power it.

    If all else fails, it aappeard to be a variant of the "Fuzz Face pedal, for which just about everything is documented on line . . .

    If this is the Protaitone / Landtone pedal kit, the seller will mail you a PDF of the diagram if you message them.

    Just to let you know you're not abandoned. I will take a look at this over the next week and make a wiring diagram for you. Hang in there help is on the way.

    It might be just me, but the battery looks like it's soldered to the DC power in jack, and I don't see any power connections going to the board.

    There is wire going from dc to input jack.

    Double check your capacitor polarities and transistor orientations. If you have a multimeter check that 3PDT switch. I've gotten bad ones before even soldering on it.

    Capacitators are ok.. transistors are ok too.. I don´t have that multimeter but i´ll ask my teacher if he can check it for me.. thanks for helping

    You are most welcome! Ok so check and check on those to things. While you're waiting... Retouch all of the solder points on the board. You want a hot iron and a "get in and get out fast" technique. Physically blow on the point you reflowed to cool down before moving on. While you're at it.. push those resistors down flush to the board. All those leads sticking up makes a bunch of tiny antennas and cause parasitic capacitance (it's a bad thing). Inspect all the pads, make sure none of the have lifted. Keep me updated on the switch if none of this works.

    One more thing that I've overlooked... Make sure your input cable is plugged in when you power it up. Just trying to cover all issues before accepting you blew it up.

    Then that means I have a vision problem. I see a BLACK wire going to the board, but I don't see any hot wire coming from the jack.
    I see only one red wire going from the battery to the jack. I don't even see what could be blocking my view of a hot wire leaving the jack.

    Well, i have to say i have no clue what are you talking about.. but i sent it to the seller and he said it’s Ok. I think the transistors are dead. Couse there is voltage on the board. I am planning to replace these ac128.
