STOY Roaring Bulb is both a clean boost and a heavy overdrive in one pedal. Use the clean side of the pedal to push your clean amp into overdrive territory and the overdrive/distortion side for your lead or full on distortion tone. If you have a one channel amp you will gain a three channel amp with this pedal. We think the clean side does color the pure signal, but in a very pleasing and enhancing way. It stacks very well with other drive pedals as well.
The overdrive side can go from light crunch to fuzz distortion, so a very versatile pedal. It is delivered with a 12 volt ac adapter so it can deliver the right warm and rich sounding tubetone you would expect from a tube pedal.


  • Level: Volume control for the output signal
  • Gain: Adjusts the amount of gain on the overdrive side
  • High: Adjusts the treble frequencies from none to ear piercing, glass shattering high frequencies
  • Low: Adjusts the bass frequencies from none to a roaring low end
  • Power Requirements: AC12V (use only the provided power supply or one similar)
  • Current Consumption: 30mA
