Just tried it on my Axe fx. I am not with my H9 right now.
It easy to recreate. The most important thing is the delay setting and how you play the pattern. Go for tempo 100 (or 300ms). Set delay to 1/8 and one repeat. Think in a dotted eight playing rhythm and play the melody on the G string alternate with the open D string as a pedal (each time one note on G string and one note on D string). Use palm mute and the second pick up position of your strat (if you have one). Than you can add a flanger effect before the delay. That's it!
Nice pattern and effect!
