Flange- First used in the 1960s, “flanging” was achieved by the use of two tape recorders that would record and play back the same program in synchronization. By slowing down one tape machine, and then letting it catch up with the other, different phase cancellations would occur at different frequencies. Since the slowing down of the tape machines was done by hand pressure against the flanges of the tape supply reels, the term “flanging” came into being.

Flanging is similar to chorusing , but modulates the delayed signal over a much shorter delay range (typically 0-12 ms). This produces a “jet airplane”-like sound. In the case of the NanoVerb's flange, the signal is split into four parts with a stereo dry signal and a separate delay section for both left and right channels with one channel flanging up while the other channel flanges down. Once again, this causes the effect to become more pronounced and dramatic.

Rotary- The Rotary effect emulates a rotating speaker. This effect was extremely popular during the 1960s and was achieved by mechanically rotating the speakers to produce complex timbral changes. The lezlie speaker system is most often used with tone-wheel organs, but is occasionally used for guitar amplification as well. When changing the speed between fast and slow, the effect will slowly ramp to the new speed rather than change abruptly, just as the original would do. Note: When using the Rotary program, the Mix parameter should be turned all the way to the right.
