GOOD ARTICLE, WORTH RE-READING
Some controls on flangers you might find...
LEVEL - (controls speed/rate of the LFO wave)
DEPTH - (ctrls depth/amplitude of LFO wave [WIDTH MXR, same as "depth"])
REGEN - (feedback/resonance)
RATE - (ctrls intensity of overall effect slow/fast cycles [Delay Time = Rate] )
MANUAL - (MXR, ctrls degree of phase shifting, possibly same as depth, but SEE Width)
TONE - PITCH
BLEND/MIX - blends clean signal with
PRESET FAVORITE (Strymon) - cool feature!
WOW/FLUTTER - originally, flangers were based on tape loops
** EXP PEDAL, can be used on some pedals to control different parameters
HARMONICS - (ADA, in addition to manual, range, speed and enhance)
SWITCH FOR LFO - selector triangle or sine wave or??
FLANGERS WITH A LITTLE EXTRA:
-Ibanez AIrplane Flanger: Manual, Speed, Range, Enhance; takeoff switch and speed
-Carl Martin's dual speed mode is foot switchable, LED flashes rate, knobs for speed depth pre-delay & feedback
-Strymon has switch 3LFO types (log, lin, through zero), switch 3 feedback types (positive, negative, pos/neg); electromechanical relay true bypass, stereo out, expression pedal with selectable knob-parameter control, favourite footswitch for setting your favourite setting -- this "fave" setting could be great, dial in a flange, then setup Lesley w/ exp pedal ctrling speed = two effects available at the drop of a stomp), standard 9v centre neg power supply 200mA, 250mA recommended, analogue in/out to dBucket algorithm A/D & D/A converters w/ 110db signal to noise, high perf DSP stuffed into compact form factor.
Maxon has proprietary MC4107D bucket brigade and JrC4558 IC chips: 5 KNOBS Range, Speed, Jet, Width, Sensitivity. Internal voltage stabilizer (mine to have it switchable to unstable)An updated version of the coveted 1970s Jetlyzer, the Maxon Vintage Jet Riser Flanger Pedal combines a VCA, VCF, and analog flanger circuit to recreate the thunderous jet-plane swoosh of that holy-grail pedal plus a variety of unique effects including filtered chorus and tremolo, jet-slap bass, and more. Featuring true bypass switching, a high-performance noise reduction system, and internal voltage stabilizer, the Maxon VJR9 Pedal combines vintage tone with modern performance.
The following adapted from HotHand's flanger (minus the ring controller):
Users can select 3 modulation sources: low frequency oscillator (LFO), sequencer, or envelope follower. Control the modulation in real time with subtle motions of your expression pedal or just play normally and let the LFO, sequencer, or envelope follower drive the sound.

MY CHEAP SUGGESTION
FLANGE & CHORUS SUGGESTIONS Envelope Flangers
Today, there are many variations on the basic effects. We have stereo effects where the left and right channels' modulation is inverted giving rise to a subtle panning effect. We also have effects where multiple delay lines and/or all-pass filters are used in parallel (and modulated at different phase angles of the modulating LFO waveform) to create rich, evolving textures, and we also have 'crossover' effects where the feeback from one channel is fed to the other (and combinations of the above) to create all manner of swirling textures.

"Barber-pole" flanging
Also known as "infinite flanging", this sonic illusion is similar to the Shepard tone effect. The sweep of the flanged sound seems to move in only one direction ("up" or "down") infinitely, instead of sweeping back-and-forth. While Shepard tones are created by generating a cascade of tones, fading in and out while sweeping the pitch either up or down, barber-pole flanging uses a cascade of multiple delay lines, fading each one in to the mix and fading it out as it sweeps to the delay time limit. The effect is available on various hardware and software effect systems.

"Differential Toggle switch. *When in Normal Mode, it uses only one bucket brigade delay chip similar to the way the MXR, BF-2, and Pearl Flangers worked. *When in Differential Mode, it adds a second bucket brigade delay chip that is in parallel and out of phase with the first BBD chip similar to the way that the A/DA and Electric Mistress flangers worked."

I'm pretty happy with Tonepad's FL301.* Very nice vintage, vaguely chorusy sounding flanger.* Very lush instead of metallic.* Plus, it uses MN3007s instead of the elusive SAD1024, so it's cheaper to build than some...

Moog Ultra Flux ... TBer upon it's hype up to unveiling: "If it's a chorus/flanger, I'm going to be right upset. I've been lusting after several different chorus/flanger/modulation pedals over the years: Polly (the Stereo Polychorus), the Fulltone Choralflanges (CF-1 and the to-be-released-two-years-ago CFV-2) and the Strymon Ola and Orbit (two pedals, but two awesome pedals). I cannot justify spending copious amounts of money on something I might not like (not anymore), and Moog has a reputation for being great, but prohibitively expensive, especially if you buy the pedal from the Chicago Music Exchange, like I did."

"From the ringing faux sitar sound to the rise and fall of jet plane sweep, flangers usually fire up very specific neurons in our brains, reminding us of certain music genres and eras often to the point of being cliché. Far more interesting to us is the way flanging and flanger like effects are used in mixdown or soundtracks to create a sense of focus, tension or space. How does this translate to a guitar effect? This really goes beyond the scope of most simple stompboxes. The Starlight DLX lets you make new sounds that conjure up imagery and emotion.

Let your creativity run wild in an whirlwind of modulated madness.
Use the trigger mode and ramp waveform to create a perfectly timed continuous rise until that jet plane goes over the horizon.
Float down the zero gravity corridor of an alien vessel with the random sample hold function.
Create droning resonance by simply maxing the regen control
Listen inside a robots brain as it contemplates turning on its human masters with the random/triangle LFO.
Does it all sound like too much? Just set the mode to manual for simplicity and explore.
Like many of our recent projects we started with the basics. We worked through several different designs, but always came back to the MN3007 running at 15 volts for maximum sweep and headroom. For functionality we used the Prometheus DLX control matrix giving you virtually infinite possibilities , but in a format where you can easily remember individual settings. We tuned the regen control to oscillate when set at maximum, and added the gate and volume control to keep more extreme sounds manageable.
