I do use a volume pedal on the clip.
The backing track is courtesy of BIAB.
In a few places I use the semitone raise on strings 1 & 7 (shown as 'V' in the tab).
Against string 5 you'll see the '*' symbol quite a lot - this is a semitone raise, which you can get by half-pedalling on A, or, by splitting the A pedal with the X (string 5 lower) lever. I use both of these techniques on the clip.
