"Antiresonant" tonestack

[notnews]

While reading through the DBA blog I came across "Paradox Effects", a pedal company based out of Tijuana, Mexico. They have 5 effects listed on their site, some of which look really cool.

One of their creations is called the Defibrillator:

Reading through the description I came across this:
"The Antiresonant Filter of the Defibrillator takes the effect through totally different dimensions; at 7 o’clock you’ll have a muff lacking high frequencies, as you turn the knob clockwise, the high end starts to appear, drastically changing the Fuzz’s hue, this tone control is HIGHLY responsive."

I understand that antiresonance in physics/EE refers to the lowest amplitude of an oscillator, or coupled oscillator. They could be using an oscillator inside the pedal and dynamically tuning it such that it destructively interferes with the incoming guitar signal in some way.. but that could potentially kill the guitar signal entirely (if enough oscillators were coupled in the pedal). Maybe the pedal has one or two internal oscillators that destructively interfere with the one or two primary frequencies coming into the pedal via the guitar, and eliminate them so that higher-order harmonics are what's distorted and outputted.

What do you guys think of this? Potentially awesome?.. or is this company just trying to use high-tech sounding jargon to make themselves sound impressive when truly it's all hollow.. or common even..

seems interesting. i found this in a quick search. not sure if this is how they do it though.
