Eventide Model FL201 Instant Flanger

Flanging may not be a popular effect these days, but back in 1975 when the Eventide Model FL201 Instant Flanger was released, it was. The Eventide Model FL201 Instant Flanger was designed to simulate true tape flanging and offered a much deeper flanging effect than anything previously available, it was widely used on many legendary recordings.


Sound studios and professional musicians who require the ultimate in versatility and quality know us by name. Eventide has built a world wide reputation by developing the original Instant Phaser. The next step – The Instant Flanger – Eventide’s latest generation of studio quality flanging equipment.

New control configuration: oscillator, manual, remote and envelope may oe used in any combination! Old model phasing units used analog circuitry to modify the frequency spectrum. Eventide’s Instant Flanger uses a true time delay circuit, producing many more nulls and thus a much deeper effect than previously available with an all-electronic unit.

To simulate true tape flanging we have introduced an effect modifier block which allows the operator to imitate motor or servo hunting “bounce”. Our exclusive ‘depth’ control will permit any desired percentage of direct versus delayed signal, and relative phase of each.
