well i have been days trying make my quasar( bass band mate) but i could get it, instead of boosting it was eating the signal, at max volumen even below unity volumen was coming out of the pedal, the strange part to me was that the gain knob really did nothing, so that was my first clue, i post on the tech help but no one said anything so today start making something and when i was chicking the schematic i saw that on the op amp in the clipping there its a cap(C3) and on the build doc was 150pf but on bass mod version it was replaced by 47nf, i thought that caps it too big for going there, so it almost eat all the signal, then replace it for a 100pf cap, and that was the big deal, lots and lots of volume boosting and gain, so i think that instead of 47nf should be 47pf or max 470pf, not so sure, but i saw that the bigger the capp in there the more bass on the output, so 470pf should be good or not??
