DOD will give you the factory schematics and BOM if you ask. Use their tech support contact form on their website. You'll be asked for a serial number on the form, so have that handy. I just asked and they sent me the schems for my FX69 and FX75C. P3pper asked for the FX33, and was given it. He posted it here: viewtopic.php?f=11&t=13948&start=40

So, if you have the actual pedal, ask them for the schem. And then please post it here!

Diodes D6 and D7 emulate a sort of cross-over distortion.
I have an FX58 and plan to bypass them to see how that changes the sound.

And maybe after that, remove D8 and D9...
That would leave only the asymmetric clipping circuit of D3 D4 D5 making it more into an overdrive instead of a distiortion as well as raise the signal volume. I did the same thing with an Ibanez MS10 and now its a nice OD pedal.

Thanks for the schematics btw!
