I was playing around with the Slow Gear on my GT8. I got a sound pretty close to that John Mayer song, "I don't trust myself loving you" in the intro. He uses a different effect, not the Boss one.
It just builds a little slower. You can almost make it sound like you're playing backwards.
John Mayer uses a Roger Linn Adrenalinn for that song.
From Wikipedia: "Most notably, unlike other guitar pedals, the AdrenaLinn specializes in beat-synced effects, including modulation and delay but also a sequencer that provides looped patterns of filtered tones, all moving in sync to its internal drum machine or to midi. Other unusual aspects of this pedal include note-triggered filter effects such as auto-wah, simulated talk box and guitar synthesizer sounds."
I don't think you'll quite nail the sound with anything other than an Adrenalinn.
