AM getting the same result :poor or lack of octave sound ,i thing that there's not enough voltage on the oscilator.maybe the schematic is wrong,becouse i check the shin ei octaver in the oscilator ,and has his on 9 volts ,instead of chopped voltage from the transistor base of this circuit,i need help in this one ,what i did wrong? The fuzz is fine.Iwas trying to get the "everyone's a winner " guitar sound .Have auditioned many fuzz octave boxes on youtube and no luck.THE fuzz part is a little like gated or sputtered on the song and a littlle octave down and then up .thx
