Modulated Monophonic Harmonizing PLL

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. The three-position switch on the Master Oscillator control panel labeled Root feeds your input to the Data Corrupters 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 Corrupters 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 Oscillators eight-position rotary switch. The Voice Mixer's Oscillator control adjusts the Master Oscillator blend.

The Frequency Modulator 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 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 Data Corrupter 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 Mixers Subharmonic control to set the lower octave volume.

Finally, (or is it?) the Square 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.

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.

Specs:
Dimensions: 5.65″ x 4.65″ x 2.25″ with knobs
Power: The Data Corrupter should be powered by a standard 9-volt DC power supply with a 2.1mm negative center barrel (not included)
Current Draw: 25mA
Input impedance: 1M
Output impedance: 1K
Switching: This device is true bypass and uses electronic relay based switching. Audio will not pass without power.

this thing is a monster. it has a ton of different settings and can go from gross and weird to disgusting and nearly incomprehensible. to begin with it's quite sensitive to input so the same settings can give expressive results based on how you play, pickup settings, tone knob... if you dial in just the square tone and nothing else, you get a brutal gated fuzz tone with no controls (just the volume). start bringing in the other two oscs and you can get freaked out subs and harmonies that eat at eachother and decay into chaotic dropping zipper tones. the sub osc can be set to follow the master or follow the input so you can get a nasty fuzz tone with a mean sub octave that's almost like a weirdly slightly busted meatbox that has some feedback loop going on. if you want something easy to use this isn't it. you'll have to sit and tweak this thing, see how it reacts, and it is a noisy beast. if you want something weird and unique, this is it.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, woodwind pads, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
  • USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year. Pricing for used electronic products is 4% of the original new selling price.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: $40 flat rate up to $2,000 of current new selling price to double the warranty from 1 year to 2 years.
  • BRASS and STRINGS: 2% of the current new selling price above $2,000.
  • WOODWINDS: 4% of the current new selling price above $2,000.
