Ambient, Distorted, Great for long Intros. First versions of this pedalboard were called "wall of sound", which also describes it ;) The one minute sample doesn't really catch the full spectrum of this, but gives an idea how it sounds. I'd say expression pedal is required, otherwise it's kinda hard i gues to get that nice swell effect. I use an FCB1010 for that. Enjoy ;)
