Mid-Fi Clari(not)

Posted by on 28 February, 2011 Leave a comment (22) Go to comments

Here’s a vero layout of the Mid-Fi Clari(not). It sounds like a really fun little circuit.

Update (13.10.2011): Mod suggestion from Milkit: “Cut the trace joining pins 1 & 8 of the LM386, join them back together with an spst switch & you have yourself a fuzz cut switch. It doesn’t cut out the fuzz totally, but it’s not so prominent, kinda becomes more of an overdriven sound.”

Update (06.08.2012): Finished this effect the other night and it’s really fun, but maybe not so useful. Those knobs needs to come off again, but other than that I’m fairly happy with it.

    Thanks for the suggestion, kevtron.

    I put an LED beside D2 to act as an indicator LED, doesn’t appear to drain voltage

    The LM386N-3 should be just fine. As for the LDR I have no idea really; you should experiment, but either will probably work.

    Hi Harald,

    Would a LM386N-3 be ok?
    Which LDR would suit better:

    Medium Light Res Dark Res
    5K 1M
    17K 1M
    24K 500K
    40.5K 1M

    Thanks

    Hi!

    Have you checked the Deluxe version?

    It has an extra Speed pot and LFO.

    I’m not that familiar with the PT2399 and you may be correct. I have built it with 10nF’s though, and it seems to be working just fine.

    hi harald,

    in this schematic: http://media.photobucket.com/image/mid%20fi%20clarinot%20schematic/midfielectronics/mid-fi_clarinot.png
    is reported that the capacitors connected to pin 7 and 8 of IC3 are 100nF (and not 10nF)..

    maybe there is a mistake?

    thanks

    Harald you should definately Build it! I only had a few minutes to try it out yesterday, but it´s the bomb!
    Thanks for your reply! I really love your work, and can´t thank you enough!

  10. Harald 23 March, 2012 at 08:52

    I haven’t built this one yet, but I imagine you only adjust it so the effect as a whole “plays well” with your input signal. If this is indeed so yours is probably good.

  11. Chris 23 March, 2012 at 07:32

    I built it yesterday, and man it´s a very inspiring pedal!

    Is the tracking knob very subtle? I barely hear a difference if i use it?!

    Thanks and keep on rocking,
    Chris

    Another great layout, worked first time. Not sure i`ll use it overly much but a fun build and it`s there should i need it.Kudos to you

  13. Daniel 8 January, 2012 at 15:53

    Another thanks for a great layout – works perfectly.

    Hi, tunelion.
    Have a look a bit further down on the layout. You’ll notice some additional wiring directions, particularly this one: “Volume 2 -> Output” indicating you should connect the volume pot lug #2 (wiper) to wherever you want circuit output to go.

  15. tunelion 9 December, 2011 at 12:40

    Hi, i was looking the layout and you forgot to write the output.
    Can you write it for me please?
    thaks

    Awesome! Thanks Harald, I’m ordering parts now and can’t wait to get started on some builds

  17. Harald 21 October, 2011 at 09:13

    Hi, Boxcar.
    You’d make a cut at either e4 or e5. And if you look at my build pictures of, say the “Flatline Compressor” or “Baja Opto-Limiter”, you’ll see examples of LED and LDR sealed together with shrink tube.

    I’m completely new to this stuff, but what is meant by “cut the trace joining pins 1 & 8 of the LM386″, what would the Alpha-Number corresponding points be on the diagram?
    Also, how are D2 and R4 sealed together if they’re so far away on the board?
    Sorry for the newb questions, just trying to figure this stuff out.
    Thanks

    Thanks for the suggestion, Milkit. I updated the post.

  20. Milkit 12 October, 2011 at 23:27

    Hi just thought I’d let you know about small & simple mod for the “clari(not). Cut the trace joining pins 1 & 8 of the LM386, join them back together with an spst switch & you have yourself a fuzz cut switch. It doesn’t cut out the fuzz totally, but it’s not so prominent, kinda becomes more of an overdriven sound.

    Loving this pedal though, so much fun! Thanks for the layout dude!

  21. Harald 4 May, 2011 at 23:30

    Thanks for letting us know, Chris.

  22. Chris 4 May, 2011 at 22:02

    This layout works great!!! Thanks a bunch!!!
