Thanks VB
I guess I better don't tell you I used the Fender reverb setting ( sh!7loads of reverb with that one. (mhh now I did)
Here is a sweeping Flanger only mix
Flanging according to wikipedia
This flanging is one specific type of phase-shifting or "phasing". In phasing, the signal is passed through one or more all-pass filters which have non-linear phase response, and then added back to the original signal. This results in constructive and destructive interference that varies with frequency, giving a series of peaks and troughs in the frequency response of the system. In general, the position of these peaks and troughs do not occur in a harmonic series.
In contrast, flanging relies on adding the signal to a uniform time-delayed copy of itself, which results in an output signal with peaks and troughs which are in a harmonic series. Extending the comb analogy, flanging yields a comb filter with regularly-spaced teeth, whereas phasing results in a comb filter with irregularly-spaced teeth.
In both phasing and flanging, the characteristics (phase response and time delay, respectively) are generally varied in time, leading to an audible sweeping effect.
To the ear, flanging and phasing sound similar, yet they are recognizable as distinct colorations.
Commonly, flanging is referred to as having a "jet plane-like" characteristic. In order for the comb filter effect to be audible, the spectral content of the program material must be full enough within the frequency range of this moving comb filter to reveal the filter’s effect. It is more apparent when it is applied to material with a rich harmonic content, and is most obvious when applied to a white noise or similar noise signal.
If the frequency response of this effect is plotted on a graph, the trace resembles a comb, and so is called a comb filter.
The name "flanging" comes from the original method of creation. Originally, a signal would be recorded to two tape machines simultaneously. The playback-head output from these two recorders was then mixed together onto a third recorder. In this form, minute differences in the motor speeds of each machine would result in a phasing effect when the signals were combined. The "flange" effect originated when an engineer would literally put a finger on the flange, or rim of one of the tape reels so that the machine was slowed down, slipping out of sync by tiny degrees.[citation needed] A listener would hear a "drainpipe" sweeping effect as shifting sum-and-difference harmonics were created. When the operator removed his finger the tape sped up again, making the effect sweep back in the other direction.
Alternatively, the track could be recorded to two matching tape decks first, then replayed simultaneously with both decks closely in sync. With this method, slowing down one deck by pressing the tape reel flange would "sweep" the flange effect in one direction, but when released the playback of that deck would remain slightly behind the other, and the effect would not sweep back. Instead, pressing the flange of the other deck would sweep the effect back in the other direction as the tape position of the decks move toward being in sync again.
This is the sweeping version (stereo sweeps) it chages quite dramaticly, that why I kept it quite low in the mix on most places
