Nerd TalkThe 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.
Master OscillatorThe Master Oscillator takes it's input from one of three sources: Unison, one octave down and two octaves down. Some frequencies are too high for the Master Oscillator to divide, therefore, shifting them down one or two octaves brings them back into the proper range (it also happens to sound super cool). These sources are referred to as "Root" and can be selected via a three-position switch. The Root is then fed into the PLL and multiplied to create one of eight different intervals over three octaves that are selected by the rotary switch to create your harmony! This harmony can then be manipulated via the Frequency Modulator section.
Frequency ModulatorThe Frequency Modulator has two modes, Glide and Vibrato. In Glide mode, the pitch will glide from note to note and the speed of the glide can be adjusted by the Rate control. At faster settings, this takes on a very cool phase shifting effect. In Vibrato mode, the pitch varies up and down to create a laser-like effect. The Frequency Modulator only affects the Master Oscillator, unless the Subharmonic Root switch is in the Oscillator position.
SubharmonicThe Subharmonic section of the Data Corrupter creates a sub octave of the Root and then divides it up into eight intervals over three octaves which are selected by the rotary switch to create your subharmonic harmony. The Root comes from one of two sources, Unison or the Master Oscillator. When Unison is selected, the Subharmonic will be a division of the square wave fuzz tone and the Frequency Modulator will have no effect. When Oscillator is selected, the Subharmonic will be a division of the Master Oscillator and the Frequency Modulator will be applied to the Subharmonic harmony.
Voice Mixer and LevelThe Master Oscillator, Subharmonic and Square wave fuzz tone all have volume controls under the voice mixer section. Use these to blend the three voices together to taste. The Level is a master volume and determines the overall output level of the effect.
TrackingThis pedal should be placed close to front of your signal chain and before any delay, reverb or modulation effect. While it will work with most bridge pickups, the neck pickup will provide the best tracking results. Precise picking and single notes will track quickly and cleanly. Chords and sloppy playing will result in chaos. There is no control over the amount of gain because it really needs to be fine-tuned to properly track. Weak signals (like backing off on the guitar volume) will lead to poor tracking and gating.
Design NotesThis 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.

When will I receive my shipment?
We ship on business days (Saturday, Sunday, and holidays are not business days). Packages ship from Mississippi, Nevada, New Jersey, or Ohio -- we cannot guarantee that any product will ship from a specific warehouse. Expedited Shipping (1-Day Air and 2-Day Air) is the only way to guarantee that you will receive an item within a certain time frame. Delivery estimates for expedited shipping options are listed on the product page for the item in question. All expedited shipments are delivered Monday-Friday.
Ground Shipping typically takes 1-4 business days from the date of shipment (for orders within the 48 contiguous United States). Residential ground and Free 2-Day shipments are delivered Tuesday-Saturday. Commercial ground and Free 2-Day shipments are delivered Monday-Friday. Make sure to select the proper address type for your address in checkout, as delays may occur if your selection is incorrect.
For APO/FPO customers, all orders ship via USPS. Expedited shipping is not available. Tracking for these orders is not available.
For customers shipping to a PO Box, the order may need to be shipped via USPS. For this reason, expected delivery dates cannot be guaranteed.
Do you ship to my location?
For most products shipping to the continental United States, customers may choose Ground, 2-Day Air, or 1-Day Air delivery. We also ship to Alaska and Hawaii; however, due to carrier restrictions, we cannot ground-ship to those states.
In addition, we ships to the following destinations, though some restrictions apply:
- Puerto Rico
- U.S. Territories
See instructions below for how to search the site by our eligible shipping destinations.
Note: We cannot change a shipping address on an order after it has shipped. If an order is returned because it couldn't be received at the listed shipping address, we will accept the return but will not refund the shipping charges.
We ship a lot of our most popular gear to Canada! To determine if item(s) ship to Canada, add the item(s) to your cart and enter your shipping postal code. Items that ship to Canada are sent via International Air, and delivery is typically 2-5 business days from the date of shipment.
Canadian orders are charged in U.S. dollars. Actual charges are dependent on your bank's conversion rate. Your bank may assess additional fees for international orders.
Although items shipped to Canada receive their full factory warranty, they must be returned to a United States service center for repairs. We're not responsible for any shipping or customs fees incurred in such a case.
We ship many items to Puerto Rico. To determine if item(s) ship to Puerto Rico, add the item(s) to your cart and enter your shipping zip code. Eligible items ship via International Air, and typically arrive 2-5 business days from the date of shipment.
We ship to APO/FPO addresses for free, though over-sized items may be ineligible. To determine if item(s) ship to your APO/FPO address, add the item(s) to your cart and enter your shipping zip code.
We ship eligible products to American Samoa, the Federated States of Micronesia, Guam, the Marshall Islands, the Northern Mariana Islands, Palau, and the Virgin Islands. Eligible items typically arrive 2-7 business days from the date of shipment.
What about customs fees?
Please be aware of customs fees such as taxes and duties, which are not included in our shipping charges. Customs fees vary from location to location. Please check with your local customs office for more information on the fees in your area. If you refuse to pay these fees, your order will not be delivered. We cannot refund shipping charges if an item is returned due to refusal to pay fees, and a restocking fee may be applied to cover the cost of return shipping. Customs fees are non-refundable.
Which items ship immediately?
Most orders ship the same business day your order is placed when you place a valid order before the shipping deadline.
Immediate shipment is available Monday-Friday. A valid order placed before 5 p.m. EST will ship the same day when using Ground or Free 2-Day shipping. Ground and Free 2-Day shipping orders placed after 5 p.m. EST will ship the next business day. Many orders using an expedited shipping method (2 Day Air or Next Day Air), and placed before 10 p.m. EST, will ship the same day.
Shipment and availability information updates from our warehouse to our website almost in real time. We are highly confident of the status of each item when you view a page. However, we do not reserve inventory being viewed or even placed in shopping carts, so we cannot guarantee an item's availability until you have placed your order. In particular, if you have been in the checkout area for more than about 10 minutes, we do recommend that you refresh the page to get the most current inventory prior to checking out.
What is a valid order?
A valid order is for a valid item at a valid price, placed with a credit card with complete and verifiable address and other information. Details.
Does immediate shipment mean immediate delivery?
Once an order is shipped, our carriers (Federal Express and UPS) typically guarantee a service time for when the order will be delivered to you. Our carriers have a very good record of delivering at their promised service time. We will ship immediately, and on all items, we will refund expedited shipping charges if the carrier's service levels for your chosen shipping method are not met.
If a product is in stock, is there any reason it will not ship immediately?
Exceptions are very unusual, but here are some examples of reasons that might prevent us from shipping immediately:
- Warehouse, call center, or web operations lose power or telecom connectivity.
- Warehouse, call center, or web operations lose capability due to adverse weather (blizzard), safety threat, or other factors.
