Lovepedal Black Magic

Haven't done a layout with board mounted pots in a while, so here's the Lovepedal Black Magic. It's a LM386 based distortion that tries to get achieve the "Brown Sound." I added polarity protection and put the LED resistor on the board as well.

    1. Sure. Just find something close. 3.3nF or 5.6nF or put two 10nF caps in series to create a 5nF cap.

    2. I actually kept 6.8nf

      Pot is the problem now i cannot find any 500ohm pot ..i kept 500kpot but when i turn in full theres a noise i cant get rid of.i think its not grounding noise..something else when i turn in full

  3. And is it 500ohm linear or is it 500k ohm?



    I cudnt find any 500 ohm linear pots

    1. You can use a 1k pot and then wire a 1k resistor from lug 1 to lug 3, which will make it a 500Ω pot.

  4. Anyway i can add tone knob in this circuit???


    And if i use all ceramic capacitor instead of film capacitor will there be any problem??? Or diffrent ?

    1. IF you want a tone control, build the Lovepedal Purple Plexi 800. Essentially the same circuit with a tone control. Shouldn't be any difference with ceramic caps.
