The main problem that I'm having with this circuit is that I don't understand completely how a photo-diode works. I would like to build a working example of this and put it into an electric guitar.
The other main problem is that I tried to put the 14 LEDs in series and none of them lit up, so I think that the problem might be that they used high efficiency LEDs in the schematic.
Any help on this topic would be appreciated.

It's also not that sensitive, I would like to make it more sensitive like this:
