This thing is for those who in love with Matamp-family amplifiers (you here a lot :) ). Here schematic of the preamp of Electric MV120 in pedal format from freestompboxes forum ( original topic ). Thats would be cool to add another cranked fuzz-like amp emu to the local collection.
I haven't built it but I have spent some time trying to make sure it corresponds to the schematic! It was quite tricky. Obviously I don't know the tapers of the pots and might have got them the wrong way around but that's easy to fix if you build it.
