Fishy

I am sort of new to the guitar (about 9-10 months), so most of what I can pick up is by ear or by visuals, but the questions I do have go something like this:

1. Was the song played in drop-tuning? The reason I ask is because to get the rise up the strings that you end on the second string with a bend before returning to the main riff idea, I start on the sixth string and walk up to the first instead on my guitar for the same sound, and I am not sure if droptuning was the reason.

2. What effects did you use for the interlude part (the one where on the video you are playing a single chord and the other guitar from the recording is playing more prominently, about 1:30 in the vid)

Really that's about it at the moment, but if you have a better resolution version of the youtube video or anything like that, I would appreciate any help you can give there. If you tab it out, please let me know. Thanks!
