It's a signal splitter with one knob for cross over frequency.

---TREB
..............>CROSSOVER ---INPUT (FULL RANGE)
---BASS


You could use to parallel fuzzes, like the low end of a muff and the buzzy high end of a Maestro. Making new, unique, unheard fuzztones. This would really be something for people who like vintage pedals, now you can blend different textures together in different ways. Vintage, with a new take.

Bassists could send all their gain to the treb and retain all low end to the bass side, and pick where they want the frequencies to cross.

Using only the bass or treb output it could also be used to cut off unwanted muddy low end or shrill highs. EQ pedal, what have you. Like a tone knob.

Soo does this exist or...

Doesn't sfx do something like that?

That's a pretty great idea. I've definitely seen a couple of custom pedals which do that sort of thing, but I can't remember who made them... I guess any clever builder could do it if you paid them enough?

I've seen a few things like this, but nothing quite the same. Would be interested in one.

This might be a completely noob thing to ask, but here goes. Does the Zvex Machine do something like this or similar? I know it uses crossover distortion, but...

If I want something like that I'll just run stereo with a different fuzz off each tap. Can mix/eq/balance in the chain without being limited by a crossover.

Crossover Distortion and Cross over EQ are two different things. Cross over EQ sets a center frequency and anything over said frequency is either cut, passed, or some how removed from the rest of the frequency information.

What the Machine does is what's referred to as cross over distortion. It happens in Class B amplification where you use two different Tubes or Transistors to amplify a signal one boosts the Positive voltage swings. and one boosts the Negative Voltage swings. The problem with that is transistors and tubes require a minimum amount of voltage to turn on and start conduting (usually around 0.7 volts +-) so during the sweep from positive to negative voltage you can enter a "dead zone" where you're below 0.7 volts positive and above 0.7 volts negative voltage. That's where crossover distortion happens. Most distortion is made by clipping the peaks and valleys of a waveform. crossover happens at the switching point in between the peaks and valleys.


Most people don't like the sound of it. very harsh and it modulates depending on the frequency being input so you get strange tones when bending notes. Amp designers compensate for this by using a "bias" voltage that keeps at least 0.7 volts at the base of the transistor. This is called Class AB amplification.


TL;DR. The machine doesn't do what he's asking. but it does do a pretty unique effect.

Cool. Thanks for the info! Sorry to interrupt the thread, but I was curious.

I don't know for sure but while visiting some blogs today I came across the VOCU Magic Blend Room



http://www.effectsdatabase.com/model/vocu/blendroom

I've been looking for something to do this for years. That Vocu thing is the only pedal I've seen. There was an old Ibanez chorus pedal that did something similar.
I want to be able to run different trems and delays on both sides to make weird birdsong noises.

I want that too!
