The Crimson Drive is a cutting and dynamic overdrive designed around a single germanium transistor and vintage germanium diodes. It creates a very open tone with excellent harmonics and a pleasing raw grit that can’t be duplicated with more common FET or opamp based overdrives. With a simple twist of the gain control, the Crimson Drive can go from a gritty Rangemaster style treble boost to a rattling overdriven sound that is reminiscent a vintage plexi style amp at full bore. Works great with single coils as well as humbuckers and has excellent clean up with your guitars volume control.

Upgrades from V1 include:
  • Added Tone control
  • Vintage black glass OC139 germanium transistors and germanium diodes
  • Lower noise floor and improved power filtering

4.37″ X 2.37″ X 1.75″ with knobs

A standard 9 volt DC power supply intended for musical instruments with a negative center 2.1mm barrel. We strongly recommend a high quality power supply with isolated outputs and good filtering to avoid unwanted noise. Will also run off a 9v battery for you olde tymee types.


  • Drive: Controls the amount of gain
  • Tone: Rolls off high end by turning counter clockwise
  • Level: Controls the output

  • Real Germanium TONE!

Simple yet effective. Killer tone! Be sure to play with your guitar knobs (Volume & Tone)... there is a Wide Range of tones that can be achieved. Try with other EarthQuaker Effects for over-the-top tones! I love to mix this effect with the HOOF FUZZ!
