Crunchbox v2 project


This is the crunchbox v2 of MI audio verified PCB layout. Added with Jack Orman's LED anti-pop circuit. http://www.muzique.com/lab/led.htm
Simple yet effective anti-pop circuit for true bypass pedals. Opamp is LM833 specifically from National Semiconductor but I use ST's version with excellent results. Try it!Remember to use IC socket.

    V1 doesn't have an internal trimmer(PRESENCE).

    Is there any chance that this layout might be faulty? Also the clipping diodes on the schematic seem to be facing opposite direction.

    This is a working layout!. About the diodes, of course it is - take a look at the pads on the LED's.

    Hey there,

    This is some awesome work you have here.

    The layout link isn't working for me. I was hoping you could send me the layouts for the crunch box, ocd, fuzzfactory, box of metal. I'v been looking for these layouts everywhere.

    My email is jeffsavoie12@yahoo.com

    for those fools who cant get it to work, i pity u.. this layout is 100% working (great too..)

    tips: capacitor type realy got to do with ur final sound... use that boxed (yellow) caps, it sound much-much more better than my expensive 'panasonic' caps..

    SQUARE pads of an electrolytic cap indicates the "+" side.

    SQUARE pads in diodes indicates the "CATHODE", banded side.

    I think you're talking about Topmay brand poly films. Mouser, Small Bear, Futurlec, and all of the usual suspects sell those.

    It on the pdf file...not really a "list of materials" type but please use your common sense. What's shown in the layout is the parts list. I really can't help if your beginner. There are some stompbox forums you might join in. Sorry.

    It works great!!
    I used 100k-B volume potentionmeter and did not use anti-pop circuit.

    Link is parts list for this layout that I used.

      I build use dual opamp like TL072, LM833, NE532, JRC4580 and LF353. They're works and have many tone character.
