WMD Geiger Counter Pro Bitcrusher Distortion Pedal

The WMD Geiger Counter Pro is now finally in the wild—and wild, it is! Maintaining all the destructive potential of the original, the Geiger Counter Pro adds a slew of new wavetables, wavetable "morphing" features, and more.

All the bitcrushing, sample rate reduction, and original 256 wavetables are maintained; however, this new version adds 256 additional wavetables with wavetable blending, sixteen programmable preset slots, randomization options, and anti-aliasing filter for taming some of its gnarlier tones. Additionally, all parameters are now MIDI controllable, and two CV/Expression inputs provide unprecedented control from analog and modular synthesizers. Oh, and then there's the Geiger Counter Pro VST: easily enabling DAW integration and easy preset management. That's right...every parameter can be automated via MIDI from a musician's DAW of choice.

Well worth the wait, the Geiger Counter Pro is the best possible advancement of WMD's glitched-out audio mangling technology.
