I have an EQD Rainbow Machine that pitch shifts from a 4th below to a 3rd above. It should be easy to figure out but it's confusing the hell out of me.
Say I'm playing an open A string what would the harmony note be if the pitch knob is turned all the counterclockwise to 4th down?
What would the harmony note be if turned full clockwise to the 3rd above position?
How can I work out the 4th down and 3rd up harmony notes for any fretted note on the neck?

My theory isn't great but I'd like to take a stab at this for my own edification... To answer your question and basically turn this into a moveable shape that you can use up and down the neck, the 4th down would be one string lower (ex. from A to E string) and down two frets. The 3rd above would be one string higher (ex. A to D string) and down one fret. That's the first "shape" I can imagine for this scenario. So, for example if you are playing a D note on the A string, 5th fret: The 4th below is the G (6th string 3rd fret) The 3rd above is the F# (D string, 4th fret) This pattern will shift accordingly when you're working with the B string... Guys, did I mess that up?  Edit: with your example the 4th below the open A would be a low D that is lower than a guitar in standard tuning goes. The 3rd above open A would be a C#, which doesn't work with the pattern I mentioned above because that would be like your D string tuned down a half step. Instead that C# would be 5th string, 4th fret. |

I do believe that a 4th below A would be E. I think a 4th below is the same note as a 5th above (hence the chordal harmonising).

It's just a guitar, it's not rocket science.

A fourth below A is E (A - G# - F# - E) (4 notes down the A Major scale, including A as the 1st note of the 4).
A major third above A is C# (A - B - C#) (3 notes up the A Major scale, including A as the 1st note of the 3)

I'm glad I put myself out there and learned something.
My thinking was the 4th of A is D (like how open A to open D is a forth away), but "below" was simply a D that's lower in pitch than said A. I neglected to think that "below" refers to going down the scale.
Thank you.

Thanks for the replies. It took the away the confusion and has made it clear :-)
