Run Off Groove Omega

Here's a nice little boost from ROG that originated from trying to design a FET-based Rangemaster treble booster. I've laid it out for a 1590a with board mounted 9mm pots. More info, schematic and sound clips can be found here.


  1. I did build this circuit but unfortunately it's not generating any signal from the guitar. All I get is buzzing when I turn up the Master pot. Also can I substitute the 47uF cap for a 4.7uF and a 1M ohm resistor like the original schematic? Please help!

  2. Okay I did manage to get this working. Just be careful how you position the transistors.

    It is verified and sounds pretty nice.
