Boss OD-1 - Dual Op Amp version

 Forgot I had the later and more common version in a folder...

For the earlier quad op amp version there is a layout HERE.

  3. I also applied 4 capacitor value changes,

    following Analogman's experiment results, who said that between the dual op-amp version (this) and the original (quad op-amp) version the sound difference can be eliminated to 90% by using the quad op-amp version's capacitor values...

    I noted the mods over this layout and posted it here:
    (I hope it is okay with you, Anders :))

    I find it extremely exciting that in today's trend-following mass-culture
    some people like Analogman (Mike) don't say: forget everything else, what you gotto have is a quad op-amp version...
    ...but experiments thoroughly with the tone, and come up with the great news that the dual op-amp version can be modded easily to have 90% of the original tone.
    And then, of course, it is great to see a veroboard layout here :)
    Thank you, BTW (!!!)
