FAC Phazer will satisfy most fans of phasing effects, and will seduce them by its rich sonic palette offer along with its elegant interface. To get the classic phase effect, the original signal is blended with a slightly out of phase copy of itself. Altering the timing difference between both signals will produce the swooshing kind of sound.

Most of the phaser units available on the market are built around this circuit topology, with their own specificities and limitations. Guitar pedals provide great sonic signature out of the box and are a great source of inspiration, but we tend to forget that built-in fx section of some hardware synthesizers are very outstanding too. FAC Phazer has the best of both worlds, all in one single plugin providing access to a lot of parameters involved in the building of the typical phasing effect.

The design development has been inspired by some pedals as well as built in phaser effects available on hardware synthesizers. This gave birth to the characters Classic and Tirus. All the parameters can be applied on both of them to reach new personal, exciting and outstanding sounds.

The presets Slow Phase Pedal, Moderate Phase Pedal, Jumpy Phase Pedal or also Fleur d’Oranger bring the pedals sound signature within your reach. On the other hand, the preset Tirus Anthem is a good start to explore the phase kind of effect you can get from synthesizer built-in fx.

A very valuable asset, which strongly contributes to the sonic palette variety, is the modulation options brought by the plugin. The LFO can run either in free mode, synchronised to the host tempo or also being defined externally by automation curves.

i’ve never been interested in a phaser before, but when i saw FAC designed one i knew it would change my mind. the sound you get from this, especially combined with alteza, are far better than i originally expected. the butterfly graphic that shows you what is happening is genuis and really lets you see how you’re sculpting your sound, it is more than what i’d ever expect from a phaser and brings new life to an older effect. you can sweep and swell your sound into new areas and get some great movement on pads, soundscapes as well as. bass and leads. don’t hesitate on phazer, it is going in my top 10

Another home run from FAC

Let me preface by saying I was never a fan of the phaser effect. Maybe that’s because there has never been a great phaser on iOS. That has now changed with Phazer. This is really bringing to life my pads and chords in ways that I couldn’t imagine, the visual feedback is also very helpful. As always, the sound is just amazing. Well done Fred, not only have you made another incredible plugin but you have changed my mind about Phaser effect.
