Eventide Instant Flanger MKII

What Instant Flanger Mk II Is For

Instant Flanger Mk II is a studio flanger plug-in designed to add movement, width, and analog texture to a modern mix. It excels on guitars (rhythm or lead), synths, pads, electric pianos, as well as vocals to create subtle doubling, stereo thickening, or a very pronounced swirling effect. In mixing, it can serve as a discreet sweetening tool, while in sound design it becomes a machine for generating spectacular comb sweeps, rhythmic movements, and expressive transitions.

Main Features

A "Tape" Character Flanger with Precise Control

At the core of the plug-in, the flanging effect relies on a modulated time delay that creates the famous comb filtering. The Depth control manages the intensity and color of the blend: at 100%, the delayed signal is added to the direct signal, and at -100% the plug-in subtracts the direct signal from the delayed signal, opening the door to more radical phase variations.

Three Instantaneous Sound Signatures

The Mode selector offers three flavors of flanging: Shallow, Deep, and Wide. This allows quick switching from a fine and elegant modulation to a deeper effect, then to an enhanced sense of space and breadth, without losing the musicality of the original.

Multiple Modulation Engines: LFO, Envelope, and Manual Control

To tailor the effect to each track, Instant Flanger Mk II combines several approaches. The Oscillator drives modulation at the speed of your choice, while the Envelope Follower makes the sweep react to the signal's amplitude, perfect for movements that "breathe" with the performance. The Manual control lets you sculpt the comb by turning the Big Knob, very useful for precisely placing a notch/peak in the spectrum or automating cinematic sweeps.

Expression and Inter-Track Interaction

The Remote mode allows assigning flanging control to a modulation wheel (mod wheel) to play the effect like an instrument, in real time. For creative mix interactions, the Side Chain function enables triggering the Envelope Follower from any project source (kick, vocal, hi-hat, etc.), to create organic and rhythmic "inter-track" modulations.

The Detail That Makes All the Difference: Bounce, Sync, Retrig, and Low Cut

Bounce reproduces a typical tape machine behavior when the capstan motor "searches" for its speed after release, adding expressive irregularity and a lively character difficult to achieve with a standard flanger. For a modern workflow, you have Sync and Retrig to fully control the oscillator and obtain tempo-locked or coherently retriggered modulations. Finally, the Low Cut control helps tame the effect by removing bass frequencies from the flanged signal, preserving the low-end foundation and clarity.
