 A DIY classic by Runofgroove. It is a Big Muff but the transistors is replaced with hex inverters.

Schematic and more info HERE.

  1. Fired Right up! Sounds and acts just like a Big Muff. Only thing
    I noticed was that the circuit only reaches unity with volume maxed. Any idea which resistors or caps i can change to get more volume?? Thanks as always!

    1. Thanks for verifying!
      For more volume, you can experiment with the 330k resistor at collumn 13. You can try a larger value but you might end up with more gain and possibly more noise.

  2. I added a 100nf cap and a 33k resistor between pins 10 & 11 according to the schematic & it works great

  4. This wasn't good for me...very quiet and had a bad oscillation/hum at full gain. ☹️
