that excels at dense swirling textures

The Incredible Flanging Machine, at its core, has the same basic 3 controls that almost all flangers have.

A rate control which sets the speed of the LFO. This is what sweeps the flanger. (LFO stands for Low Frequency Oscillator)

A depth knob which sets the size of the LFO. This sets the amount of sweep, or technically the amplitude of the LFO.

And a feedback control, sometimes called color, which sets the level of feedback that is returned back to the input. This increases the flanging sound, think more swirly.

The Incredible Flanging Machine adds to this simple concept, by creating a multi flanger. There are three flanger sections and three feedback loops that are all synchronized to the same LFO. The LFO in The Incredible Flanging Machine is very precise and can operate at very low speeds to achieve a smooth and creamy flange effect.

There are two switches that add additional flavoring to the flanger. Switch 1 adds a pre delay so the flanging can cross thru zero. The thru zero effect is not as dramatic as a single flange would be since there are three waves all crossing zero at different times.

Switch 2 turns on the third feedback loop, and also allows the feedback 2 knob to control the level of feedback 2 and 3.

Go Super Swirly Mode by chaining the two sides. The left and right side audio are completely independent, so you can plug the output of one side into the input of the other. Then the one LFO controls a six headed swirly beast.

The Incredible Flanging Machine also has a clean/ flanged control so the effect level can be easily controlled.

All of this in super quiet stereo unit that is built to last many years.

The Incredible Flanging Machine Controls

 
Mad Science Lab Flanger

The Rate Knob adjusts the speed of the LFO that sweeps the flanger. This is a free spinning knob. The blinking of the green and red LEDs indicate the speed.

The green LED on the left will be always on at the lowest speed, and the red LED on the right will be always on at the fastest speed. The other LED will continue to blink.

When turned on the LFO is set at its slowest speed ( .15 HZ or about 6 seconds per cycle) The red LED will on for 3 seconds, then off for 3 seconds while the green LED is steady.

6 Complete turns of the knob clockwise will take you to the fastest setting, about 20Hz

 

 

The left side control knobs

The rate knob is the only free spinning control.

The depth knob adjusts the range of the sweep for the flanger. This control adjusts the maximum size of the LFO that modulates the flanger.

If this control is set low, the LFO will be smaller and the flange will have less sweep. At lower settings the SW1 switch for pre delay will have no effect, because the delay is never going as low as the pre delay amount.

The feedback 2 knob adjusts the amount of feedback for the second delay line.

When SW2 is ON this knob adjusts the feedback level for delay lines 2 and 3.

Higher settings will emphasize the sweeping of the flanger.

The feedback knob adjusts the amount of feedback for the first delay line.

Higher settings will emphasize the sweeping of the flanger. The feedback 1 and 2 knobs will bring out different frequencies in the audio.

S1 turns on the Pre Delay. This adds a small amount of time to allow the flanger to go through the zero delay time like a reel to reel flanger can. This switch has no effect if the depth control is set below half because the LFO is only modulating a small amount at a higher delay time then the pre delay time.

Up Pre Delay ON

Down Pre Delay OFF

The switches S1 and S2 are used to add additional coloring to the sound. They are subtle changes that also depend on the settings of the other controls.

Note, the passing through zero effect is not as pronounced because of the multiple waves of flanging. The three waves pass thru zero at at three separate times. This creates a more nuanced small wave of thru zero events.

S2 turns on a third feedback loop. This level, along with the Feedback 2 level, is then set with Feedback 2 control.

This switch has no effect if the Feedback 2 control is set to 0.

Up Feedback 3 loop turned ON

Down Feedback 3 loop turned OFF

This control sets the amount of the flanger versus input signal. When set fully counter clockwise or to 0 (clean) the output matches what is input to the unit.

All the way clockwise the flanger effect is at maximum.

Line In 1/4 Switchcraft jacks

These inputs are for line level inputs, or almost any other low level input.

They can not be directly connected to a guitar, bass or turntable. The Flanger works great with guitar or bass but it cannot be the first device connected to the instrument, because of the demands of a magnetic pickup.

For best results with guitar or bass, use it as the second or later device with foot pedals. Another great choice, is to use it in a stereo effect send and return loop, on a pre amp or amp.

Line Out 1/4 Switchcraft jacks

These Outputs are line level, matching the input levels when the Clean/Flanger knob is set to 0 or clean.

There is an analog output amplifier driving these outputs so they can power long cables, and they have some jam.

   

SUPER SWIRLY MODE

To get even more flanging, go into Super Swirly Mode.

Plug into the left input with a mono source, then plug the left out into the right in and take the right out to your mixer or amp.

Basically, plug one side into the other to chain the 2 flangers into a 6 headed flange monster.

 

 

Technology

The Incredible Flanging Machine uses a 24 Bit Digital signal processor operating at a 48K sampling rate to create a super clean flanging machine.

A Mad Science Lab custom designed analog output filter and analog amplifier insure a smooth and creamy output for your flanging pleasure.

 

ROHS Compliant No hazardous materials or chemicals

The circuit boards are made and assembled in Oregon. The cases are drilled and painted in Oklahoma. Final assembly is done in California.

The power used by this unit is very small.

Multi flanging
OK so we made that term up, but not the idea, one of the first units to multi flange was the original Electric Mistress. (1976-1981)
The Electric Mistress used the SAD1024 dual analog delay line IC chip to create two linked flanger lines, and then add them together with feedback. Unfortunately, the chip is long gone, and newer bucket brigade devices have only one delay line. We acknowledge the inspiration and influence designer David Cockerell and Electro-Harmonix have had on the flanging world. We have an original Electric Mistress in the lab, and no, The Incredible Flanging Machine is not emulating the Electric Mistress, its taking the idea to the next level, or two.
