Cyclone is an all analog phaser effect voiced after classic phaser designs of the past. Crazy Tube Circuits set out to emulate the phasing notches – frequency shifts and the behavior of the original unit that each of the voicings is modelled after. With the addition of extra controls, not part of the classic designs, a whole range of classic and non-classic uses become available making it an ideal texture machine with unparalleled harmonic richness.
