ADA Flanger

There is only one king when it comes to flangers, The Analog Digital Associates model created in June of 1977. Designed by David Tarnowski, it was enclosed in a heavy cast metal housing heavier than a brick. It sported 5 knobs - Threshold, Manual, Range, Speed, and Enhance. It even had a control for even and odd harmonics with an output for a footpedal that could control the range of the sweep. The first unit utilized a Reticon SAD1024A Bucket Brigade chip but was revised later to the Panasonic MC3010 chip. It was the only flanger of it's day to house a built-in compressor and bandpass filter which gave it the unique sound. It's voltage controlled oscillation could sweep a signal faster than any of it's predecessors. When it came to extreme flanging no other company came close. It's a shame they discontinued making the unit to focus on the trendy rackmount digital processors of the day.

DOD 670 Flanger

Hot on the heels of the MXR big box professional effects David Oreste Di Francesco(DOD) started his offering in 1974 in Salt Lake City,Utah. The analog effects company was later bought out by Digitech and renamed Division of Digitech(DOD) but later repurchased by Harmon International again. The integrity of the original lineup still holds-up today and are still a bargain on the used market. The 670 flanger caught on when Eddie Van Halen stepped on his MXR black box for the song Unchained. This box can pull off the main riff of Barracuda in all it's analog splendor. The led on the device blinks with it's throbbing flanging rate. It has 4 knobs to dial in airplane sounds and metallic sounds. It can also do the watery chorus effect too with the proper tweaking. It was a classic for all it's shimmering swirling flanging goodness. For more info DOD's current offering see....http://www.dod.com/
