Create outrageous effects with the ultimate stompbox flanger.

Revered as “the Holy Grail of Flangers,” the A/DA Flanger took on mythical status in the late ’70s and early ’80s with its deep and colorful brand of analog flanging. Equal parts extreme, musical, and versatile, the A/DA Flanger is easily the most intense sounding pedal flanger ever made.

Developed by Brainworx, and officially endorsed by A/DA and its founder Dave Tarnowski, the A/DA Flanger plug-in is an exacting emulation of this iconic unit, exclusively for UAD-2 hardware and UA Audio Interfaces.

Add stunning bucket-brigade analog flanging to guitars, synths, vocals, drums, and more

Create wild analog flange effects, unobtainable with any other flanging device

Exploit plug-in-only features like, host-syncable flanging speed, Wet/Dry Mix control, dual Stereo modes, and more

Craft subtle ripples, metallic ring modulation, or jet plane whooshes with a legendary, one-of-a-kind pedal

Mythic Modulation

Mythic Modulation

Powered by the Panasonic MN3010 bucket-brigade circuit, the A/DA Flanger delivers everything from faux steel drum sounds to ultra-wide, slow, arcing contour for unmatched texture and resonance. And while most flangers offer a 20:1 time delay ratio, the A/DA Flanger offers a whopping 40:1 ratio. “When it sweeps up, it sounds like it sweeps to zero time delay,” says creator Dave Tarnowski. “It actually goes to infinity, which is what true tape flanging sounds like.”

Infinite Horizons

Infinite Horizons

The A/DA Flanger plug-in also captures the original’s unique feature set. Heady functions like the built-in noise gate, along with the Even/Odd Harmonics switch and the Threshold control — which makes the effect more dynamic the harder the input source — the A/DA Flanger plug-in emulates the original’s expressive, mind-bending possibilities.

Plug-In Only Features

Plug-In Only Features

The A/DA Flanger plug-in also offers features not found on the original hardware like Wet/Dry Mix, tempo sync to your DAW, dual stereo modes for ultra-wide modulation, and the ability to choose between the slightly grainier sounding 1979 A/DA Flanger, or the reissue unit from 2009.

Unison<sup>™</sup> Technology for UA Interfaces

Silk and smooth if used subtly

One of the best ways to get a chorus type sound. Most of chorusing gets laid on too thick, but this is a fantastic choice for subtle chorusing depth.

Missed this sound

I am a straight to the amp guitar player but was not always like this , flanger was my first pedal ever. Happy reunion, realistic sound that brings good memories

Great flanger!

I had a guitar part I really wanted to “bite” with the tone. I threw I small amount of the modern flanger and it was awesome!

Very Impressed!!

Demo’s this and thought it was good — but now that I’ve really made use of it I am blown away with how good it is!!

Sounds like what I remember.

I still have one from the '70s in storage but I didn't want to go digging it out at the time!. It sounds great on my Rhodes. Just like what I remembered.

Nice supplement as a real-time effect

This Flanger is very different from UA's MXR emulation. Really nice to have in UA arsenal and it is a Unison plugin!

Perfect emulation

this is a great emulation, try this on high hats and of course guitares and synths, it brings a nice dirt to the mix and if you use the 1979 version you get even less range & more dirt. Too bad it is more expensive here than at plugin alliance where you can often get it for 30$. the only interest is that you can track with here if you own an Apollo. I'd give 4 stars but this goes to 3 because of the price (again).

Great Flanger

I was looking for a flanger effect. Looked at a number of different native plug-ins. Tried this one and fell in love with the sound.

Not my favorite flange, but it works solid

I got this for a project and it didn't work as well as I thought. I ended up using the Valhalla SpaceModulator instead.

A/DA Flanger ROCKS!

I LOVE this thing! I own several hardware flangers and this really does, "hit me," the way a flanger should. I was mainly impressed by how as I turned the "mix" level up, the saturation increased and it of coarse sounded thicker but didn't over resonate as it increased, AWESOME! I hear such a difference in the stereo field between the 2009 and 1979 models, it really is like having two pedals. This could also be used on a mix buss, which is what was after, so Get it. It is and has been my go-to flanger for guitar and overall mix effects. LOVE IT!

Best flanger i've ever heard.

The two models have their own distinct feel. Various controls to really shape the sound. Incredible and light on DSP. Worth the money.
