Mid-Fi Electronics Clari(not)

Here's the Clari(not) from Mid-Fi. It's a delay/vibrato/fuzz... thing that's pretty cool, and the sibling of the Pitch Pirate Deluxe. It uses an LM386 amplifier that pushes a fairly standard PT2399 delay and an optical vibrato. I've laid it out for on-board pots mounted from the solder-side and you should be able to squeeze it in a 1590B. Schematic can be found here.

    1. That's a good place to start. You'll probably want to socket it in case it needs any tweaking.

  2. Woops something went wrong there. Anyway, I wanted to say that out of all the PCB manufacturing guys your circuits most definitely have the coolest names! And the circuits are great too ofcourse ;) Keep up the good work!

  3. Great job for publishing such a beneficial web site. Your web log isn’t only useful but it is additionally really creative too.

  5. Hello!
    I just finished this project, great pedal!
    I find two mods, that make sound better:
    - replace cap between 9-10 legs of 2399 from 100nF to 680nF for more repeats
    - replace 1K LED resistor to 2,7K get more range of vibrato
    - yes, socket for LDR-LED is good

    And I have one question: how add control pot for fuzz?

    1. I found a 2k linear pot (wired as a variable resistor) between pins 1 and 8 on the LM386 works great.

    2. Thanx! Its helps, but some fuzz still present on low strings, I think it may be from 2399 or one of the caps...

  6. why I have a fuzz sound all the time in effect mode? I did that schematic like is in this page. Any solution? Thank u!

    1. verified from brazil! this layout have some fuzz on sound, in the next that i build i will try cutting the trace coming off of pin 1 of the LM386. works great

  8. Hello everyone here

    Then here, I built the pedal with some modifications suggested above -

    Hello everyone here

    Then here, I built the pedal with some modifications above. I used Panasonic FC and Wima MKP for the capacitors. Good sound! I can now compare the Clarinot with an original Seppuku Kassette. My Clarinot sound full, heavy but sweet with good bass. Kassette is more harsh. Maybe it's because Kassette is made from fucking cheap composants, i dont know. Ok ok.

    I have a question : are the three pots "depth", "delay" and tracking" in the good sens ? They look inverted, no ?

  9. Just completed mine.

    I used an LDR that was sold by an aliexpress vendor as 1M but i haven't measured 1m from one of them even completely covered?

    For the LED I used an old Agilent ultra-bright red bordering on orange. DOT rated for signal light use. I don't remember much about the specs, bought them a long time ago, but i think they have a very narrow viewing angle. Vf is 1.83ish.

    Delay knob seems to work backwards (clockwise makes it faster).

    I added a switch to toggle the fuzz but now that i think about it, I have some B5K pots with integral normally-off switch. I might see what that can do for me.

    I didn't do any of the other mods but i might go back in and try them.

    Thanks very much!

  11. hello guys. i have a little question about this one. built it yesterday and it is "running" but my led, from the ldr, is not lighting up. i tested the led and i'm shure it is ok. mesured some values and i have no voltage on the anode pin of the led. its not supposed that the led receives voltage? in my newbbie mind, the effect to fully function, the led should blink and the tracking pot should control the peed of the bliking... i'm i wrong??

  12. to take off the fuzz i have isolated the pin 8 of the LM386; no more fuzz, but have some "overdrive" that i belive become of the pin 1, but i liked of this way

  13. I Just finished, works, but not like I spected, Will try different Led and ldr.
