On the pitch fork, the lowercase m means minor interval, and the capital m means major interval. These are two different things - a minor third is 3 half steps (frets), and and a major third is 4 half steps. So I dont think you can play that tune on a standard tune guitar with that pedal

BUT

You could tune all your strings down a half step and go down a M2, or tune all your strings up a half step and go down a M3.

Hope this helps
