Modulated Monophonic Harmonizing PLL
THINK: Experimental / Analog / Synth

  • Finally a widely-available harmonizing PLL / synth pedal for electric instruments!
  • Eight upper octave + harmony programs
  • Eight subharmonic + harmony programs
  • Square wave input signal
  • Selectable modulation options include “Glide” (portamento) and Vibrato

The Data Corrupter is a monophonic analog harmonizing PLL with modulation. It takes your input signal and brutally amplifies it into a crushing square wave fuzz tone that is then multiplied, divided and modulated to create a wild, yet repeatable, three-voice guitar synthesizer.

The Master Oscillator is the central nervous system at the heart of the Data Corrupter’s cyberpunk hive mind. It feeds your input to the signal harvester in its original octave (Unison), one octave down (-1) or two octaves down (-2) for maximum compatibility with your preferred instrument and frequency register. Once you’ve chosen your input octave, then the Data Corrupter will perform its calculations and spit out an analog synthesized frequency, which can be pitch-bent for portamento or vibrato sounds by the Frequency Modulator! From there, you can blend in one of eight Subharmonic intervals up to three octaves below the input and mix in a square wave fuzz tone for maximum data corruption.

CONTROLS

The Master Oscillator (1) is the central nervous system at the heart of the Data Corrupter’s cyberpunk hive mind. The three-position switch on the Master Oscillator control panel labeled Root (2) feeds your input to the signal harvester in its original octave (Unison), one octave down (-1) or two octaves down (-2). Use the Master Oscillator’s Root Switch to fine tune the Data Corrupter’s tracking response for maximum compatibility with your preferred instrument and frequency register. Once you’ve chosen your input octave, the Data Corrupter will perform its calculations and spit out a synthesized frequency, the octave and/or interval of which may be selected via the Master Oscillator’s eight-position rotary switch.

The Voice Mixer’s Oscillator Control (3) adjusts the Master Oscillator blend.

The Frequency Modulator (4) applies pitch-bend modulation to the Master Oscillator. In Glide mode, you’ll hear a smooth portamento as each note slides into the next. In Vibrato mode the pitch modulates up and down for a retro sci-fi laser effect.

The Subharmonic (5) assimilates the input signal into one of eight lower octave programs between one and three octaves below the original. For a more stable lower octave, set the Subharmonic’s Root Switch to the Unison position, which divides the Square Wave input signal, and removes the Frequency Modulator from the Subharmonic signal path.

To unleash the cracked machine lurking within the mainframe, set the Subharmonic Root Switch to Oscillator and try not to look away as the sonic malware you just installed mangles your input signal into the sum and difference of both the Master Oscillator and Subharmonic with the Frequency Modulator applied to the upper and lower octaves.

If you think you’re brave enough, set the Subharmonic Root Switch to Oscillator and try experimenting with different Master Oscillator and Subharmonic programs to wind up the doomsday clock and inch ever closer to the Singularity. Adjust the Voice Mixer’s Subharmonic Control to set the lower octave volume.

Finally, (or is it?) the Square (6) control located top-left on the Voice Mixer blends in a fuzzed-out square-wave take of your input in its original octave. That’s it. These aren’t the droids we’re looking for. Move along.

NERD TALK

The heart of this pedal is based around a CMOS Phase Locked Loop (PLL) IC. In a nutshell, the PLL takes your input signal and compares its phase and frequency against an oscillator, generates an output proportional to their difference then feeds it back to the oscillator. This then causes the oscillator to lock onto the input signal and generate a synthesized frequency. Pretty cool, right? This synthesized frequency is referred to as the Master Oscillator on the Data Corrupter. 

DESIGN NOTES

This device takes its inspiration from the Electrax Synthax and the “Basic Frequency Synthesizer” by Ray Marston. Neither of these were really intended to be guitar effect pedals and a lot of work went into creating the Data Corrupter to provide excellent tracking and long sustain. We think you’ll find it more expressive and accurate than pretty much any other PLL based effect pedal around.

    So easy to install. It was my first time using drywall anchors and it was a breeze. Only the middle screw is in a stud and two other screws in anchors. They are very sturdy. Very pleased with this purchase. I bought a second set for our second bathroom too.

    These are beautiful. Great choice
    Color: Black, Size: 24"W x 6.5"D, 2Packs
    I initially had brought these and had to return them, because I brought the wrong size. I returned them and got the correct size. I love them, they are very sturdy and well made. They are easy to install, looks great and the size was perfect too. They are great and are worth every penny. I DEFINITELY RECOMMEND THEM and will be getting another pair.

    Decent enough, but needs better anchors
    Color: Rustic Brown, Size: 27.5"W x 6.5"D, 2Packs
    The included wall anchors are brittle. One out of 8 would shatter just on screwing them into drywall. All of them shatter and strip from driving the screw in. That said, the bracket holds, and the shelves are nice for dry locations. Thin fiberboard with thin vinyl veneer, tilted very slightly towards the wall. Each kit comes with a magnetic level, and each shelf comes with an extra screw, anchor, and securing screw. Easy to intuit how to install, but includes easy instructions for those who do best with visual examples. I got 8 shelves and am content with them.
