There's a big local reggae band that has a jem-playing guitarist down here too!
-there's also a local reggae band that has a guitarist that uses an ESP George Lynch purple tiger with reverse stock...
...Ages ago I watched the 'classic albums' for Bob Marley's 'catch a fire' record. They interviewed a session player who played on the record. His name eludes me, but he sounded like he was from the southern states. he played a 335 through a fender on that record.
But yeah, anything works. I've heard SGs through blackface/silverface fenders sound really good. If I was playing reggae I'd probably grab my tele or semihollow and use my Mesa or Victoria. I'd grab a phaser too.
