“Acoustic guitar is actually my favorite instrument to hear it on. In the ‘A’ position, it lends itself to more kind of ‘60s rock and roll acoustic. If you move it over into the ‘B’ position, you get a lot more weight out of the guitar. And the brilliant part of this is that, if I want someone to double the acoustics, I can easily change the sound by switching from ‘A’ to ‘B’.”
