Two Electro-Harmonix Holy Grail Reverb pedals were used at once to get the cathedral-like sounds that ramp up to the crescendo of “The Mansion,” and that song’s secret weapon was a Walrus Audio Janus—a tremolo/fuzz that McDowell describes as “completely blown-out and insane sounding. It entirely changes your tone. There are two joysticks to control the fuzz and tremolo separately, and I was down on the floor playing with those as I recorded.”more
The joys sticks are fun to use, less intuitive than a straight out expression pedal but of course you cannot change the depth on the effect with an expression pedal. Wide range of fuzz tones, it's one of my favourites as far as fuzzes go. Tremolo very good with the joy stick for instant speed changing. Although I would say if you're looking for a trem thats very accurate when you manoeuvre it this isn't really it. It's more like an old amp style trem.
