Try 2 cents at a time though, to clearly hear a difference. Changing pitch by cents, or even a fraction of a cent can make a difference. Moving from 13.0 to 13.2ms will change the stereo phase a lot.

Like I stated before, try 13ms delay +/- & go from there. For stereo separation & spacial effects, you want to play subtly. This gives varying degrees of effect, depending how much you utilize each effect. When you run a mono dry & a stereo time & pitch shift, you are playing w/ phase, time & pitch shift. Stereo simulation, by time, is playing w/ phase. When you shift the frequency, it helps prevent phase cancellation of specific frequencies, because those frequencies are not being reproduced any longer.

When you shift the timing of 1 channel, you start putting that signal out of time, which also puts it out of phase.When you have an identical frequency, out of phase 180º, it cancels out the other sound. When looking at sound, you have a (sound) wave. Personally, I like to got around +/- 10 cents (but always do each one slightly different) and I adjust delay to taste but typically go within 10 - 40 ms (again, always different on each side).Ĭlick to expand.I was at the Dr when I typed this. So you end up with slightly delayed signal in addition to slightly detuned, again just another way to fatten up the sound.
DETUNE PEDALS PATCH
Typically delay settings are offered as well in a detune patch (just like using a delay patch with no repeats). Try something drastic like 50 cents to see what is happening, it will sound bad but it will clearly show you are lowering/raising pitch. In a detune patch with + and - are you adding slightly higher and lower pitches to the signal to fatten it up. The 5150 album has this effect all over guitar and vocals, listen to the top of "Good Enough" for example.Ĭent is a small measure of note pitch: "Twelve-tone equal temperament divides the octave into 12 semitones of 100 cents each".

Harmony intervals, or Detune range controlled by the expression pedal. Like a chorus but without the obvious "swirl" of modulation.ĭefinitely a BIG part of EVH's later tone. DigiTech Whammy DT Pedal is a Classic pitch shifting pedal allowing you to step up or down in 7 half steps. Robert Plant's vocals on the later Zep albums is another example. I'm a big fan of detune type effect (for vocals in particular).
