Interesting. I think it may have been used for his “main” sound through the clean channel because he had some crunch in his rhythm tone and seemed to turn the unit off and turn on the red channel of the amp for leads. His lead sound wasn’t super sustainy and fluid as on albums.
One thing that did blow me away was watching him do the first section of the solo to How Will I Laugh. It’s a crazy two finger tapping thing. On one lead he dramatically bent a note down that I would have bent up. I’m not sure why but it sounded amazing.
