Name that effect:

[Creamyapples1]

I'm not a huge fan of Buckethead but I love this song. I'm a total effectswhore and I can't place it. Curious if anyone can identify the effect used around 4:04. Thoughts, Suggestions, Brand, Model?

If I had to guess, I'd say he has a delay on, then used a whammy pedal to bend the pitch up a full octave.
