I like the fact that it does not use diodes, maybe the note decay won't be super smooth this way... but at least it will sound a little different, actually it's like a low gain rat to me

As you will see it's not very original: I took inspiration from the rat, hot cake, buffalo pfuz, rez overdrive (pinkjimi also noticed this simple ad nice overdrive).
Since I finally downloaded and started working with diylayoutcreator (god bless him) I can at least share a readable perf layout (sorry but never tried vero); the layout can be very easily translated in pcb too (sorry but I gave up etching). Well at least it's the first project made by me wich is really ready to build... on perf.
