"KarmaDrive" PCB question - Zendrive/Serendipity

Hey,

maybe you can help.
I have this "KarmaDrive" PCB (Zendrive), want to build one into a 2-in-1:

Here's the BOM:

(Karma Drive PCB Mount Pots)
And the project page: http://www.reddit.com/r/KarmaDrive/
I don't remember where I stumbled over all this, I ordered the PCBs without checking anything.

I have built one Zendrive on vero before using the Tagboardeffects layout:
http://tagboardeffects.blogspot.de/2012/01/hermida-zendrive.html
and it sounds right to me.

Now, looking at the parts values of the Tagboard one, and also Madbean's serendipy (http://madbeanpedals.com/projects/Serendipity/docs/Serendipity_ver.5.pdf), and comparing them to this OSH Park one, there are some differences. This one has eight capacitors (optional power filter, unnecessary?), the others have seven. Other differences too, some slightly different resistor values etc.

Could someone who can read schematics better and quicker than me maybe say if this will still sound like a regular Zendrive, or which values to use in which position for this PCB to make it into a correct one, I'd still like to use this PCB as it's very compact.

Thanks a lot!
