For years this vintage noise maker was next to impossible to find until it was wisely reissued, only to be promptly discontinued again? Whatever the case, the ADA Flanger is, and always has been, the undisputed king of the entire flanger universe. Five knobs and one switch control threshold, manual, range, enhance, and even/odd harmonic duties. What separates the ADA from ordinary flangers is a threshold feature which allows softer picking to stay uneffected while heaver picking activates the effect. It's a very responsive and engaging twist on what is normally a very static effect. The immense scope of this pedal's sonic capabilities are practically endless. Sure, you'll get the typical swirling filter sweeps, jet aircraft swooshes, and pinging metallics but with the added dynamics of your playing intensity. Combined with other pedals like distortions, tremolos, and phasers, the ADA Flanger can turn your sound upside down.
