Sorry, posted this to wrong are before, should be here. HI all. Maybe someone can advise me on this. I've build a Fuzz Face clone but it had big hum with my normal power supply so I've put 470uf cap and 470k resistor on the power supply input. Hum is gone and I only get 0.5V Voltage drop so that don't bother me but is ok to put high value caps like this? It's not going to eat up battery or something other I've not noticed? Also is there a way the get rid of that cratching pot fuzz noise? My does it and I've noticed the original Fuzz Face does to. Thanks for any advice Jim
