 RotorDrive is my first attempt at building a solid state DIY Guitar Overdrive. Design is based on a dual transistor gain stage for power overdriving.  RotorDrive is my first attempt at building a solid state DIY Guitar Overdrive.

 When "DRIVE" switch is closed, unit is in Overdrive mode, with highly distorted sound and weird harmonics. When "DRIVE" switch is closed, unit is in Overdrive mode, with highly distorted sound and weird harmonics.

 +The sound of this medal is somehow quite "brute force". I recommend to combine it with a tone shaping network like the [[basic tone filter]] proposed here.

 +The volume output pot is optional, recommended mainly for assembly in a case on a final product.

 Generally, this schematic can be easily extended on use. Consider having a good power supply regulation, according to the gain of this dual stage. Generally, this schematic can be easily extended on use. Consider having a good power supply regulation, according to the gain of this dual stage.
  
 +Note : R13 should not be installed, it has been added for simulation purpose. The output of this pedal is the tip of the volume potentiometer.
