In 2002, Hammond was named "34th coolest person in the world" by NME. He usually plays a yellow and black Fender Precision Bass and a red Burns Bison bass, but also has two semi-acoustic Epiphone basses, one in yellow and black sunburst, and a pink banjo, the other in red and black. He is also fond of acoustic basses, of which he has two - one with a natural finish, the other with a black gloss. Both are Epiphones.
Hammond has a son and two daughters with his girlfriend Anna; Nico (born 2004), Sonny (born 2007) and Sandy Blue, born 19 December 2008.
