aron	Re: broken big muff, need help John, I am guessing that you DO have the IC-based big muff and this is the correct schematic: http://www.geocities.com/CollegePark/Library/1355/bigmuffopamp.gif When you say yours has 2 ICs, please give use the IC part numbers. One of them could be a DUAL op amp (the 4558 IS a dual). The 741 is a single, so physically when you look inside you would see only TWO physical IC chips since one of them is TWO inside of one. Try following the schematic, it must be the same one.
