Recent History:
January 2, 1996 ---ADA Amplification Systems announces the reissue of its original 1978 FLANGER. It is a true reproduction of the original 1978 floor pedal circuitry and packaging. Hailed as the king of flangers by music columnists and players, the ADA Flanger is capable of producing a wide range of vintage and modern sound colorations, dramatically enhancing the effect of any amplified instrument, voice or percussive device.
The unique capabilities of the ADA Flanger are numerous and astounding, including effects such as rotating speakers, chilling vibrato, "jet sounds," resonance modification, intensified studio flanging and incredible notch filter matrices, to name a few.
When people as about analog flangers, this one comes up often, I've seen it mentioned at the MOOG forum.
