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. For an interesting discussion on this unit see
