Danelectro CD-1 Distortion

After checking a few things out, this turns out to be slightly modded Maxon DS-830 (thanks johnk for noticing). The 47p, 10n and 180n cap values are measured on board, so i'd suggest using sockets for those and see what values work the best for you. Anyway. This should be safe to build.

Playing around with the original, this may be one of the most underestimated drive pedals around. You won't be saving any money building one for yourself, but this way you'll be able to tweak the gyrators and clipping diodes to suit your taste.

  1. miro i have a real one too, do you need me to take any measurements or anything to help verify your schematic?

    one a side not, i think all of the "cool cat" series pedals are not give the props they should. they are all great pedals, even the metal, despite that i'm not that crazy about it as a high gain pedal, it's still pretty good.

    1. I do have the original, so if needed, i'm able to take more measurements. I just thought this would be a fun way to see if fi gt it right :)

      Most of these are good. This one did surprise me though.

    2. not a problem. i don't know if i'm going to have a chance to attempt this one before someone else verifies it, but you know me, anything i can do to help i'll do.

  2. what are the gyrators? Sorry for the simple question just wanna be sure

    1. The simplest answer would be - Both treble & bass controls are active gyrators (Q3-Q4). The caps around those determine the frequency cut/boosted by the controls.

    2. it's no wonder it sounds good, since to me, It looks like a Maxon DS-830 with a few component changes.

  3. has anyone verified this yet? wich one will have more gain this or the maxon DS-830? Is there a resistor on this circuit that can be changed to give this more gain or less?

    1. You can increase the Gain pot value for more gain

    2. This will have slightly more gain than DS-830. Upping the 3K going to drive lug 2 for 10-22K will take the lowest settings out and result in slightly added gain.
