Earthquaker Devices Wave Transformer Eurorack Module Now Available

Earthquaker Devices has introduced The Wave Transformer, a ‘Transfiguration Oscillator’ for Eurorack modular systems.

Here’s what they have to say about it:

“We decided to go deeper into the weird and wonderful world of modular synths, this time creating a complex single oscillator module with seven audio outputs, a host of exciting features, and a unique Wave Transformation circuit, all for the modest price of $199 USD.

The Wave Transformer’s method of wave shaping differs from other complex oscillators in that it is not based upon classic wave folding, as is common in West Coast synthesis, or filtration as is common in East Coast synthesis. Rotating the Transform control will vary the Complex output from a simple waveform to a complex, gnarled mass of audio mutations.”


  • 100% analog circuit
  • Over 8 octaves of pitch tracking starting from A -1 (13.75 Hz), covering more than the full range of a traditional piano keyboard
  • 7 simultaneous waveform outputs
  • Dedicated attenuators / attenuverters for each CV output
  • Exponential and Linear Frequency Modulation inputs
  • Hard and soft sync inputs
  • Pulse width control between 0%–100%
  • Fixed -1 octave 25% duty cycle sub octave pulse output
  • Sub Square output switchable between 1 and 2 octaves down
  • Complex Source mute switch allows simultaneous control of volume and timbre up to audio rates via the Transform CV output
  • Dimensions: 20HP / Max Depth: 1 inch (25.4 mm)
  • Current draw: 90 mA max from the +12v rail, 90 mA max from the -12v rail
  • Standard 10-pin Eurorack power connector with a marking to notate the negative pins
  • Reverse Voltage protection
  • Over-current protection on all outputs
  • Skiff friendly – protrudes less than 1 inch (25.4 mm) behind the panel with the power header installed
  • Lifetime warranty
