What do these two pedals too to the sound? Technically or simply speaking.
Chorus provides a modulated de-tuning of the signal that gives the impression that there is more than one instrument playing at once in unison.
Flange is somewhat similar in that it is still a modulated de-tuning, but it is much more prevalent and makes a "sweeping" sound. Flange was originally produced by placing 2 reel-to-reel tape machines that were in sync with the same source. you'd alternately press on one flange then the other, slowing one set down and then allowing it to catch up while slowing the other down.
Really to get a better idea, look on any of the major e-tailers (musiciansfriend.com, music123.com) or some of the effects manufacturers to get sound samples as to how these effects sound.
Flangers mix a varying delayed signal (usually about 5mS to 15mS) with the original to produce a series of notches in the frequency response. The important difference between flanging and phasing is that a flanger produces a large number of notches, and the peaks between those notches are harmonically (musically) related. A phaser produces a small number of notches that are evenly spread across the frequency spectrum. (http://users.chariot.net.au/~gmarts/fx-desc.htm#Flg)
True vintage chorus works the same way as flanging. It mixes a varying delayed signal with the original to produce a large number of harmonically related notches in the frequency response. Chorus uses a longer delay than flanging, so there is a perception of "spaciousness", although the delay is too short to hear as a distinct slap-back echo. There is also little or no feedback, so the effect is more subtle. (http://users.chariot.net.au/~gmarts/fx-desc.htm#Cho)
just buy an EBS unichorus
it has a built in chorus , flanger and pitch modulator
by far one of the best pedal IMO
For Flange to the nth degree, see/hear:
