| Kursad K | ProCo-Rat schematic. Is it correct? http://www.kilback.net/homebrewtweaks/pedals/pcratc.gif This is the strangest stompbox schematic I've ever seen. I cant see how it works in spite of the almost zero opamp bias voltage. It looks like as if there is a miswiring around the first transistor, 1uF capacitor and the 1K resistor. Is this schematic correct? Kursad |

| Tim Escobedo | That first transistor stage is all wrong. This is more like it. http://www.muzique.com/schem/pcrat1.gif |

| Kursad K | This thing makes strange oscillations when the volume pot is connected. (I've removed it). Yeah I know. Star grounding and lead dress etc... But since this isn't a tube amp, I'd thought I could break the rules a bit while building a stompbox. I was wrong.This is the first stompbox I've built and it's working fine except the volume pot.
