According to Becker himself, he used a JB-loaded Les Paul at Bob Rock's studio on that particular song.
In fact, it was that experience with the JB in the Les Paul that prompted him to reach out to Seymour Duncan to see about getting his own custom pickup made!
The specific amp he used on that song is anyone's guess, but Becker said he used 8 different Marshalls on that album and no other brands of amps.
He also played straight into the amp with no added effects. Any "studio magic" we hear was added after the tracks were recorded.
