I have several phaser plugins, but - to be honest - not many of them really give me the sounds, which I expect from or associate with a typical phaser.
Quite the opposite here, already the default setting sounds convincing, the tones are widely individually adjustable and the sound quality is very good.
I even am considering of buying the whole Modula Suite, if the quality of the other plugins is similar to this one. (I have just downloaded the tremolo demo and it also impressed me in the same way as the phaser did. Good tones, no frills.).
For the quality prices are fair, even more the ones for the suites / bundles.
