Thank you all for your kind remarks.
Robert, I'll take your observations about the drums into account when I revisit this. This was the first song I ever did with AD2, so I'll take some time with this to get it right.
Mark, thanks for listening. The vocal processing in this comes from Izotope Nectar, and it reminds me of a Pink Floyd song that I like. I made sure that the dry vocal was sounding good to my ears before applying the f/x.
Freddy, thank you for your kind words. I hadn't thought of ZZ Top, but now that you mention it, I know what you mean. This f/x was new for me, and I just wanted to give it a try.
