Boss DS-1

[Styxx]

I'm building a pedal that incorporates the Boss DS-1. Can anyone tell me why the insides of the pedal I have look something like this:

When the only schematic I can find, in a wide variety of locations, is this:

Note that the first picture is not my own, it's actually a slightly modded circuit. However, the point still stands, there's at least 8 transistors in the pedal I have and none on the schematic, plus a whole load of extra caps and resistors. Is this all to do with the switching? Or is it something else?

That schematic bogus. Here's the real one:

The schematic on the freeinfosociety site don't include the buffers and FET switches of the Boss DS-1. You can say it's a "simplified" version of the DS-1.

If you're building your project from scratch, it would make your life easier to go with the freeinformationsociety schematic.
